Write an equation in point-slope form of the line that passes through the given points, then write the equation in slope-intercept form.
(-9,7), (6,2)
Answer:
Point-slope form: [tex]y-2=-\frac{1}{3} (x-6)[/tex]
Slope-intercept form: [tex]y=-\frac{1}{3}x+4[/tex]
Step-by-step explanation:
So, first, we need point-slope form.
Point-slope form: [tex]y-y_1=m(x-x_1)[/tex]
In this form, m is your slope and [tex]x_1, y_1[/tex] is your point.
We have two points, so let's find the slope.
Slope formula: [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
The y_2 and y_1 points can be interchanged, but order can't be changed (a y_2 can't go with an x_2).
For this problem, (-9,7) is going to be the x_2, y_2 pair.
[tex]x_2[/tex] = -9
[tex]y_2[/tex] = 7
[tex]x_1[/tex] = 6
[tex]y_1[/tex] = 2
Let's put the values into the formula.
[tex]\frac{7-2}{-9-6}[/tex] = [tex]\frac{5}{-15}[/tex] = [tex]-\frac{1}{3}[/tex]
The slope is 1/3. Going back to point-slope form, let's put the slope in.
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-y_1=-\frac{1}{3} (x-x_1)[/tex]
Now, lets put our x_1, y_1 point in.
[tex]y-2=-\frac{1}{3} (x-6)[/tex]
This is our point-slope form.
Now, to convert this to slope-intercept form, multiply everything out.
[tex]y-2=-\frac{1}{3}x+2[/tex]
Add two.
[tex]y=-\frac{1}{3}x+4[/tex]
This is our slope-intercept form.

A builder wants to nail a 2 1/4 foot extension to a board that is 7 9/12 feet long. How long will the board be after her work? Express your answer in lowest terms.
A reasonable estimate for this problem is approximately
( A. 6 B. 9 C. 10 ) feet.
A common denominator to use is ( A. 12 B. 16 C. 16) .
The board will be
A. 5 2/3 B. 6 C. 9 5/8 D. 10 feet long.
Answer:
CADStep-by-step explanation:
2 1/4 = 2
7 9/12 = 8
2 + 8 = 10
2 1/4 = 9/4 = 27/12
7 9/12 = 93/12
27/12 + 93/12

Hello! :)
To solve your equation, we will first simplify both sides of the equation
x + 2/3 = -1/6
Now, we will subtract 2/3 from both sides
x + 2/3 - 2/3 = -1/6 - 2/3
x = -5/6

Adult tickets for a concert were $5 each and student tickets
were $2 each. A total of 980 tickets, worth $3460, were sold.
How many adult tickets were sold?
Answer:
500 adult tickets
Step-by-step explanation:
Let adult and student tickets be x and y.
The number equation is
x + y = 980
The value equation is
5x + 2y = 3460
Let's multiply the first by two and subtract it from the second...
5x + 2y = 3460
-(2x + 2y = 1960)
and we get
3x = 1500
x = 500 adult tickets
y = 480 student tickets

17. You have $75 in your bank account. Each week you plan to deposit $8 from your allowance and $10 from your paycheck
The equation b = 75+ (10 + 8)w gives the amount b in your account after w weeks. How many weeks from now will you
have $195 in your bank account?
weeks.
There will be $195 in the account after
(Type a whole number.)
Answer:
60 weeks
Step-by-step explanation:
195 = 75 + (10 + 8)w
195 - 75 = (10 + 8)w
120 = (10 + 8)w
120 = (2)w
120 ÷ 2 = w
60 = w

Trent is simplifying the expression 47 × 13. He claims he can solve the problem by multiplying 47 × 10 and adding it to the product of 47 × 3. Select the answer that best explains whether or not his strategy is correct. Trent is incorrect, because one group of 13 is not the same as one group of 10 and one group of 3. Trent is incorrect, because he would need to add the 3 to 47 before multiplying it by 10. Trent is incorrect, because he must first round 47 to a number that is easier to multiply. Trent is correct, because one group of 13 is the same as one group of 10 and one group of 3.
Answer:
Trent is correct because one group of 13 is the same as one group of 10 and one group of 3.
Step-by-step explanation:
47 x 10 = 470
47 x 3 = 141
470 + 141 = 611
47 x 13 = 611

Eric pays the mechanic $80
per hour plus $350
for parts to get his car fixed at the car repair shop. His bill is $1,110
If h
represents hours of work, write an equation that could be used to find the number of hours the mechanic worked on Eric's car.
Answer:
80h+350=1100
Step-by-step explanation:
he pays the mechanic $80 per hour therefore 80h and pays $350 for the parts in total he spends $1100. If the equation is solved it will be
9 hours. (the answer came out to be 9.375 exactly)
