I really need help no one else has been able to help me

1) Considering the points A (-8,-5) B( 3,11) C (-2,-14)
A Rotation 180º clockwise follows this rule:
Pre-image Image
(x,y) -----> (-x,-y)
2) So those are the coordinate of the image:
A (-8,-5) B( 3,11) C (-2,-14)
A' (8,5) B'( -3, -11) C' (2,14)
