Question

If two line are perpendicular and one has a slope of 1/6, what is the slope of the other line ?
A.1/6
B.-1/6
C.-6
D.6

Answer 1

Do you know the formula to calculate this? :)

Answer 2

Well, m x m(perp) = -1. So you have (1/6) x m(perp) = -1.

Answer 3

It would be C.
To find the slope of a line that is perpendicular you use the opposite reciprocal.
So you flip the fraction and change the sign

Answer 4

I thought it was D

Answer 5

@ambermarie151 Rearranging the equation gives m(perp) = -1/(1/6) or -1(6) = -6
