Find the slope intercept equation of the line

Answers

Answer:

I know that the y-intercept is 5

Step-by-step explanation:

because the line goes through 5

Answer:

y = -4/5x + 5

Step-by-step explanation:

You need the equation y = mx + b

the y intercept is 5 which is b

You just need to pick any point on the line and use those coordinates to plug into the equation for x and y to solve for the slope (m)

I will use point (5, 1)

So plugging in that coordinate and the value for b in the equation

y = mx + b is (1) = m(5) + 5

Solve for m m= -4/5

so plug m and b back into the equation y = mx + b

y = -4/5x + 5

Step-by-step explanation:

18+7x=19

More than in math represents addition, and the "a number" phrase is your variable, which is x.

(this is for if you're supposed to solve the equation)

7x=19-18

7x=1

x=1/7

Answers

I thinks A 5/8 hoped this helped

Answer:

C. 5/24

Step-by-step explanation:

John = 3/8

Tim = 1/3

Kevon = ?

---------------------------------

3/8 = 0.375

1/3 = 0.333

0.375 + 0.333 = 0.708

0.292 is left

---------------------------------

5/8 = 0.625 - wrong

9/24 = 0.375 - wrong

5/24 = 0.208333 = 0.293

Expression 1

O The two expressions are not equivalent because when x2, the two expressions do not have the same value.
O The two expressions are not equivalent because when they are simplified, they do not have the same coefficients for
the andx terms.
O They are equivalent because the sum of the constants is the same in both expressions.
O They are equivalent because when X- 2, the two expressions have the same value,

Answers

First I wold simplify the expressions by combining like terms so #1 becomes 9x-1 and #2 becomes 9x-1

Once you’ve done this you can see that the two expressions are actually the same and therefore equal to each other.

The best description of the equivalency would be D
Just because the sum of the constants are equal doesn’t mean the expressions are. There could be different amounts of the variable (that’s why you should always simplify )
