Answers are pre image points to image points after 180 rotation
R = (-6, 7) ➡️ R’ = (6, -7)
S = ( -3, 5) ➡️ S’ = (3, -5)
T = ( -2, 0) ➡️ T’ = ( 2, 0)
U = ( -8, 4) ➡️ U’ = (8, -4)
Step by step
The rule for a rotation by 180° is (x,y)→(−x,−y)
So we plot the pre image coordinates, then we change the sign on our x and y coordinates and re-plot them on the graph
