Answer:
-1/5
Explanation:
I am assuming that y=2 means a point (0,2) which is what my answer is based off of. If that is wrong please tell me
Slope is y2-y1/x2-x1 so we will do -3-2/1-0 = -5/1 = -5 so the slope of the original line is -5.
The slope of a perpendicular line is the negative recripocal of the original slope which would be -1/5.
