37:prime 65:composite 71:composite 82:composite
I think it would be 72+4x=400
400-72= 328
328/4= 82
So the answer would be 82=x
-5/1 is the slope so the answer is -5 because you pick 2 points and use point slope formula or
y1-y2/x1-x2
It would be -5. assuming that back is negative and forward is positive, Kyle has moved a total of 5 spaces back
