For the given pair of points, find the equation of the line y = ax + b that goes through the points by solving a system of
equations.
-(-8, -8) and (-7, -6)
A) y = 2x + 8
B) y = 2x - 24
C) y = 4x + 8
D) y = 2x - 8

Quizplus · Accepted Answer

The slope of the line is (y2 - y1) / (x2 - x1) = (-6 - (-8)) / (-7 - (-8)) = 2. The y-intercept is b = y1 - mx1 = -8 - 2(-8) = 8. So the equation of the line is y = 2x + 8.
