Question

What is the slope of a line that is perpendicular to the line shown?
(3, 3) (-3, -1)

Answer 1

-3/2

Explanation:

The line shown has slope ...

... (y2 -y1)/(x2 -x1) = (-1 -3)/(-3 -3) = -4/-6 = 2/3

The slope of the perpendicular line is the opposite of the reciprocal of this:

... -1/(2/3) = -3/2
