Question 9 OT 10

The lines shown below are perpendicular. If the green line has a slope of -2/3
. what is the slope of the red line?

Answer 1

(3/2)

Explanation:

A perpendicular line has a slope that has the negative inverse of the reference line. The green line's slope of -(2/3) becomes (3/2) for a perpendicular line. The red line has two points we can use to calculate slope, just to check.

(-3,-5) and (5,7)

Rise = (7 - (-5)) = 12

Run = (5-(-3)) = 8

Slope = (12/8) or (3/2)
