Question

A line passes through the points(-8,-7) and (-4, -4) what is the equation of the line in slope intercept form

Answer 1

Explanation:

(y - y1)/(y2 - y1) = (x - x1)/(x2 - x1)

(y + 7)/(-4 + 7) = (x + 8)/(-4 + 8)

(y + 7)/3 = (x + 8)/4

4(y + 7) = 3(x + 8)

4y + 28 = 3x + 24

4y = 3x + 24 - 28

4y = 3x - 4

y = 3x/4 - 1
