write an equation of the line, in point-slope form, that passes through the two given points.

y = -2x - 2

Explanation:

1. Find the slope (m) using the equation (y2-y1) / (x2-x1)

(y2-y1) / (x2-x1)
(-12 - 12) / (5 - -7)
(-24) / (12)
-2

2. To find “b”, plug in one of the points into the equation (e.g. if you choose the point (-7, 12), plug in -7 for x and 12 for y)

y = -2x + b
12 = -2(-7) + b
12 = 14 + b
-2 = b

3. Rewrite the equation using the information you have

y = -2x -2
