Answer:
3
Explanation:
The slope of the line shown can be found from the formula ...
m = (y2 -y1)/(x2 -x1)
m = (0 -1)/(0 -(-3)) = -1/3
Any line perpendicular to this will have a slope that is the opposite of the reciprocal of m. Its slope will be ...
-1/m = -1/(-1/3) = 3
Every perpendicular line will have a slope of 3.
