Question

What is the slope of the line perpendicular to the equation

Answer 1

Y=3x+2  slope = 3
perpendicular, slope = -1/3

answer is C) -1/3 

Answer 2

A perpendicular slope is a negative reciprocal of the initial slope.
So you take the initial slope and flip the numerator and denominator (3/4 becomes 4/3, 4 is really 4/1 so it becomes 1/4)
Then you change the sign, so if it's positive it becomes negative and vice versa.
3/1 becomes -1/3
