Answer:
1. C' ( -12, 1 )
B' ( -7, -2 )
2.
Original Coordinates = R ( -8, 4 )
O ( -2, 4 )
P ( -2 , 8 )
E ( -8, 8 )
(A) Reflected (y = x) = R ( 4, -8 )
O ( 4, -2 )
P ( 8, -2 )
E ( 8, -8 )
(B) Reflected (y = -x) = R ( -4, 8 )
(not sure if it's O ( -4, 2 )
supposed to be after P ( -8, 2 )
previous reflection) E ( -8, 8 )
Explanation:
1. C ( -6, 2 ) → ( -6 - 6, 2 -1 ) → ( -12, 1 )
B ( -1, -1 ) → ( -1 - 6, -1 - 1 ) → ( -7, -2 )
2. Reflecting over y = x line --- ( x, y ) → ( y, x )
Reflecting over y = -x line --- ( x, y ) → ( -y, -x )
