Question

What is the slope of a line that is perpendicular to the line to the line represented by the equation y=1/3x+4

Answer 1

C.

Explanation:

Perpendicular slope means it's the opposite, meaning the perpendicular slope of 1/3 is -3 because -3 = -3/1. [note: if it's positive it should come out negative and just the opposite if it's a negative (the fraction should also be flipped)]
