Help me please will Mark answer Brainy-est

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 )

Step-by-step 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 )

probability for j is 1/4

while

a is 1/6
