In the xy-plane, line ℓ is perpendicular to the graph of the function ƒ(x) = 5x – 2. Line ℓ could be the graph of which of the following functions?
---
The given equation has a slope of 5 so any line perpendicular to it
must have a slope of -1/5

==================
A.g(x) = –5x
B.g(x) = -(1/5)x
C.g(x) = x – 2
D.g(x) = (1/5)x
E.g(x) = 5x
