Line p passes through points (-1,2)and (-3,-4).What is the slope of a line perpendicular to p?

Answer 1

First, need to calculate the slope going through these point.

m=(y₂-y₁)/(x₂-x₁) Plug in the values

(-4-2)/(-3-(-1)) Simplify

-6/-2 = 3

To find the slope of the line perpendicular to this, it is the negative reciprocal m = -1/3
