Factor it should be
8(v-8)(v+7)
Answer:
undefined
Step-by-step explanation:
We can find the slope of the line using
m = (y2-y1)/(x2-x1)
= (-2 - -10)/(-1 - -1)
= (-2+10)/(-1+1)
= 8/0
When we have a 0 in the denominator the slope is undefined

Subtract the 7 and eliminate the 7 then subtract from 13 on the other side.
