Hey there! Remember that perpendicular lines are the negative reciprocal to the original slope. With that in mind, the best way to find the slope is by using equation m=y2-y1/x2-x1, so then if we plug this in we get:
-4-3/2-(-1)
As -4 is our y2, -3 is our y1, 2 is our x2, and -1 is our y1.
You should get -7/3, that’s the original slope. Since this is a perpendicular line we MUST FLIP it and CHANGE THE SIGN.
So our FINAL answer would be: 3/7
Hope that helps!!!
