Question

Write an equation of the line that passes through the points (-9, 4) and (-10,8) in

Answer 1

Answer:

y = −4x − 32

Step-by-step explanation:

Answer 2

Answer:

y = -4x - 32

Step-by-step explanation:

First, find the slope using rise over run (y2 - y1) / (x2 - x1)

Plug in the points:

(y2 - y1) / (x2 - x1)

(8 - 4) / (-10 + 9)

4 / -1

= -4

So, the slope is -4. Plug in the slope and a point into y = mx + b, and solve for b:

y = mx + b

4 = -4(-9) + b

4 = 36 + b

-32 = b

Then, plug in the slope and y intercept into y = mx + b

y = -4x - 32 is the equation of the line
