and
so

and you rationalize denominator by multiplying numerator and denominatr by
so that gives--

Your answer is 
Answer:
o(-2,-1)
Step-by-step explanation:
Let point A be initial point and A' be terminal point.
A(-7,3), A'(x,y) and V=(5,-4)
V=(Xf-Xi,Yf-Yi)
(5,-4)=(x-(-7),y-3)
(5,-4)=(x+7,y-3)
5=x+7. -4=y-3
5-7=x. -4+3=y
x=-2. y=-1
A'=(-2,-1)
<em>On coordinate grid X goes first then Y.</em>

Y2-y1and then x2-x1 that’s how learned how to find the slope of a graph
I hope this helps. If you are still confused just tell me and I’ll explain it again
