What is the equation in slope-intercept form of the line that passes through the point (2,-2) and is perpendicular to the line represented by y=2/5x+2?

Question

A) y=5/2x-7

B) y=5/2x+7

C) y=-5/2x-3

D) y=-5/2x+3

Answer 1

D) the slope has to be the negative inverse of 2/5 which is -5/2, that means either C or D

then plug in the point y=-2, x = 2 into either C or D. It only works with D

-2 = (-5/2)(2) + 3 = -5 + 3 = -2
