Find a linear function whose graph has the given slope and y-intercept.
-Slope 2, y-intercept (0, -8)
A) f(x) = 2x + 8
B) f(x) = 2x + 2
C) f(x) = -8x - 2
D) f(x) = 2x - 8

Question

Quizplus · Accepted Answer

The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. Given a slope of 2 and a y-intercept of -8, the equation becomes y = 2x - 8, which matches option D.
