Cool question (Although it is tough somewhat)
1st step is to visualize the change from C to C'
we have C'(8,-3) and C(3,-8) supposedly for C because it doesn't show any real values.. Nonetheless
from C to C' there has been a rotation of 90 degrees clockwise
proof:
Clockwise 90 degrees rotation law : (x,y) --> (y,-x) and it proves the change from C to C'
Therefor
all left to do is estimate the B point coordinates and implement the law of rotation
B(8,-7) Now implement a rotation of 90 degrees clockwise
we would get
B'(7,-8)
Hope that helps
