Question

What is an equation of the line that passes through the points (-2, -7) and (-1, -3)?

Answer 1

y = 4x + 1

Explanation:

Answer 2

y = 4x + 1

Explanation:

Find slope, rise over run

`(y_(2)-y_(1) )/(x_(2)-x_(1)) = (-3--7)/(-1--2) = (4)/(1) = 4`

find y intercept by plugging in one of the coordinates in y=mx+b, including m=4

-7 = 4(-2) + b

1 = b
