Part A
For this case we have the following transformation:
And for this case we can conclude that this represent a transformation Through the origin. The best answer would be:
A) 180 º clockwise rotation about the origin
Part B
For this case we have the following coordinates given:
(-7,0)
(-2,2)
(-3,8)
And if we apply the transformation we got:
(7,0)
(2,-2)
(3,-8)
