Which equations represent the line that is parallel to 3x - 4y = 7 and passes through the point (-4,-2)? Select two
options
AT
VX
Oy=-3x + 1
0 3x - 4y = -4
0 4x - 3y = -3
Oy-2 =(-4)
Oy +2 = (x + 4)
Answer:
The equations represent the line that is parallel to 3x - 4y = 7 and pass through the point (-4,-2) are:
[tex]y+2=\frac{3}{4}\left(x+4\right)[/tex][tex]3x - 4y = -4[/tex]Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptGiven the line
3x - 4y = 7
writing in the slope-intercept form
4y = 3x - 7
dividing both sides by 4
4y/4 = 3/4x - 7/4
y = 3/4x - 7/4
Now, comparing with the slope-intercept form of the line equation
y = 3/4x - 7/4
The slope of the line m = 3/4
We know that parallel lines have the same slopes.
Therefore, the slope of the parallel line is: 3/4
now we have,
The point (-4, -2)
The slope m of parallel line = 3/4
Given the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line and (x₁, y₁) is the point
substituting (-4, -2) and m = 3/4 in the point-slope form of line equation
[tex]\:y-\left(-2\right)=\frac{3}{4}\left(x-\left(-4\right)\right)[/tex]
[tex]y+2=\frac{3}{4}\left(x+4\right)[/tex]
Thus, the equation in the point-slope form of the line equation is:
[tex]y+2=\frac{3}{4}\left(x+4\right)[/tex]
Simplifying the equation
[tex]y+2=\frac{3}{4}\left(x+4\right)[/tex]
Subtract 3 from both sides
[tex]y+2-2=\frac{3}{4}\left(x+4\right)-2[/tex]
[tex]y=\frac{3}{4}x+1[/tex]
Multiplying the equation by 4
[tex]4y = 3x + 4[/tex]
[tex]3x - 4y = -4[/tex]
Therefore, the equations represent the line that is parallel to 3x - 4y = 7 and pass through the point (-4,-2) are:
[tex]y+2=\frac{3}{4}\left(x+4\right)[/tex][tex]3x - 4y = -4[/tex]The equations that represent the line that is parallel to 3x - 4y = 7 and passes through (-4, -2) are: y + 2 = 3/4x + 3 and y = 3/4x + 1
What is the Equation of Parallel Lines?If two lines are parallel, the slope (m), in their equation in slope-intercept form (y = mx + b) would be the same.
Rewrite the equation, 3x - 4y = 7 in slope-intercept form
-4y = -3x + 7
y = -3y/-4 + 7/-4
y = 3/4y - 7/4
The slope (m) is 3/4, therefore, the slope of the line that is parallel to 3x - 4y = 7 and passes through (-4, -2) would be: m = 3/4.
Substitute (a, b) = (-4, -2) and m = 3/4 into y - b = m(x - a)
y -(-2) = 3/4(x - (-4))
y + 2 = 3/4(x + 4)
y + 2 = 3/4x + 3
y = 3/4x + 3 - 2
y = 3/4x + 1
The equations that represent the line are:
y + 2 = 3/4x + 3 and y = 3/4x + 1

Write the equation of the line passing through the given point that is perpendicular to the
given line.
12. y = - 4x + 7: (4,2)
Answer:
The equation of the line passing through the given point that is perpendicular to the given line y = - 4x + 7: (4,2) is [tex]\mathbf{y=\frac{1}{4}x+2 }[/tex]
Step-by-step explanation:
Write the equation of the line passing through the given point that is perpendicular to the given line.
y = - 4x + 7: (4,2)
The equation of required line will be in slope-intercept form [tex]y=mx+b[/tex] where m is slope and b is y-intercept.
We need to find slope and y-intercept
Finding slope:
When two lines are perpendicular their slopes are opposite reciprocal of each other. [tex]m_1=-\frac{1}{m_2}[/tex]
So, slope of given line = -4 ( Comparing with [tex]y=mx+b[/tex] m = -4)
Now, slope of required line will be: m =1/4 (Opposite reciprocal)
Finding y-intercept
y-intercept can be found using m = 1/4 and point (4,2)
[tex]y=mx+b\\2=\frac{1}{4}(4)+b\\2=b[/tex]
So, we get b = 2
Now, Equation of line
Equation of line having slope m = 1/4 and y-intercept b = 2 is:
[tex]y=mx+b\\y=\frac{1}{4}x+2[/tex]
So, the equation of the line passing through the given point that is perpendicular to the given line y = - 4x + 7: (4,2) is [tex]\mathbf{y=\frac{1}{4}x+2 }[/tex]
NEED HELP ASAP! WILL MARK BRAINLIEST TO THE RIGHT ANSWER!! Line A passes through the points (-3,-4) and (-6,-5). Write the equation of the image of A after a dilation with a scale factor of 2, centered at the origin. Write your answer in slope-intercept form.
y=
Answer:
[tex]\displaystyle y=\frac{1}{3}x-6[/tex]
Step-by-step explanation:
Dilation of a Line
Given a line that passes through points A(-3,-4) and B(-6,-5). We'll apply a dilation with a scale factor of 2 centered at the origin by multiplying each coordinate by 2. The points map to:
A'(-6,-8) and B'(-12,-10)
Now we find the equation of the line passing through A' and B'.
The equation of a line passing through points (x1,y1) and (x2,y2) can be found as follows:
[tex]\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
Substituting:
[tex]\displaystyle y+8=\frac{-10+8}{-12+6}(x+6)[/tex]
[tex]\displaystyle y+8=\frac{-2}{-6}(x+6)[/tex]
[tex]\displaystyle y+8=\frac{1}{3}(x+6)[/tex]
Operating:
[tex]\displaystyle y=\frac{1}{3}x+\frac{1}{3}*6-8[/tex]
[tex]\displaystyle y=\frac{1}{3}x+2-8[/tex]
[tex]\boxed{\displaystyle y=\frac{1}{3}x-6}[/tex]
The Reeds are moving across the country. Mr. Reed leaves 5 hours before Mrs. Reed. If he averages 40mph and she averages 50mph, how many hours will it take Mrs. Reed to catch up to Mr. Reed?
Answer:
It will take 20 hours for Mrs. Reed to catch up with Mr. Reed
Step-by-step explanation:
Given that:
Mr. Reed leaves 5 hours early.
Speed of Mr. Reed = 40 mph
Distance covered in 5 hours = 40 * 5 = 200 miles
Let,
h be the number of hours and D be the total distance.
D = 40h + 200
Speed of Mrs. Reed = 50 mph
D = 50h
For catching up, both distances will be same
D = D
50h = 40h + 200
50h - 40h = 200
10h = 200
Dividing both sides by 10
[tex]\frac{10h}{10}=\frac{200}{10}\\h=20[/tex]
Therefore,
It will take 20 hours for Mrs. Reed to catch up with Mr. Reed

Marcos reads 3, books in 1 3/4 weeks.
At this rate, how many books does Marcos read in1 week?
Enter your answer in the box.

[tex]x = \frac{12}{7}\ books[/tex]
Step-by-step explanation:
Given
[tex]3\ books = 1\frac{3}{4}\ weeks[/tex]
Required
Number of books in 1 week
Represent the number of books in 1 week with x.
So, we have:
[tex]3\ books = 1\frac{3}{4}\ weeks[/tex]
[tex]x = 1\ week[/tex]
Cross Multiply
[tex]x * 1\frac{3}{4} = 3 * 1[/tex]
[tex]x * 1\frac{3}{4} = 3[/tex]
Convert fraction to improper fraction
[tex]x * \frac{7}{4} = 3[/tex]
Multiply through by [tex]\frac{4}{7}[/tex]
[tex]x * \frac{7}{4}*\frac{4}{7} = 3 * \frac{4}{7}[/tex]
[tex]x = 3 * \frac{4}{7}[/tex]
[tex]x = \frac{12}{7}\ books[/tex]
Hence: 12/7 books were read in a week

Chris has just sold a home valued at $85,000. Her
normal commission for the homes that she sells
is 8%. Determine the amount that Chris will make
on the sale of the $85,000 home.
Answer:
Amount of Chris' commission = $6800
Step-by-step explanation:
Given that:
Value of the house sold by Chris = $85,000
Percent of Chris' commission = 8%
Amount of Chris' commission = 8% of 85000
Amount of commission = [tex]\frac{8}{100}*85000[/tex]
Commission = 0.08 * 85000
Commission = $6800

C. -1 ≤ y ≤ 1
Step-by-step explanation:
The range is the vertical extent of the graph.
Here, the graph goes back and forth between y = -1 and y = +1, so the range is the interval -1 to +1, with those values included. Written as an inequality, it is ...
-1 ≤ y ≤ 1
Written in interval notation, it is ...
[-1, 1] . . . . using square brackets to indicate the end values are included
__
Curly brackets { } are used to delimit a set. That is {-1, 1} means the y-values consist only of -1 or 1 and nothing else. Obviously, that is not the case here.
_____
So, the steps are ...
1) understand the vocabulary, so you know what the question is asking
2) be able to read a graph and identify high points and low points
3) recognize the various ways the answer can be written
4) locate one of those answer possibilities in the list of choices offered

Answer:
a(y-1)/1+y
Step-by-step explanation:
Given the expression y = a + p/a-p
yo are to make P the subject of the formula:
Step 1: Cross multiply
y = a + p/a-p
y(a-p) = a+p
Step 2: open the bracket
ya - yp = a+ p
Step 3: Collect the like terms
ya - a = p+ yp
ya - a= p(1+y)
a(y-1) = p(1+y)
Step 4: Divide both sides by 1+y
a(y-1)/1+y = p(1+y)/1+y
a(y-1)/1+y = p
p =a(y-1)/1+y
Hence the required solution is p = a(y-1)/1+y
