Answer:
m = 3/2
Step-by-step explanation:
The slope of a line is m = rise / run.
As we move from P to Q, x increases from -8 to -5 (3 units) and y decreases from -10 to -12 (2 units). Hence, the slope of this line is m = rise / run
and m = -2 / 3.
Any line perpendicular to this line has a slope which is the negative reciprocal of this.
(slope of perpendicular line) = -1 / (-2/3) = 3/2
