Find an equation in slope-intercept form (where possible) for the line.
-Through (-4, -1), m = -1.5
A)y = 1.5x - 7
B)y = -1.5x + 5
C)y = 1.5x + 5
D)y = -1.5x - 7

Question

Quizplus · Accepted Answer

The slope-intercept form is y = mx + b. Given m = -1.5 and point (-4, -1), substitute into y = mx + b to find b: -1 = -1.5(-4) + b, solving gives b = -7. Thus, the equation is y = -1.5x - 7.
