Answer:

Step-by-step explanation:
First, we need to find the slope, which is defined as the change in y over the change in x:

To find a slope that's perpendicular to that, we just take the negative reciprocal of that slope, which is  .

So you will use slope formula which is m = (y2 -- y1) / (x2 -- x1)
-1 minus -7=6
13 minus -8=21
Remember it changes to a positive Keep,Change,Change
So its 6/21
Or 1/4
