Two similar polygons are shown below: A coordinate grid is shown from positive 10 to negative 10 on the x-axis and from positive 10 to negative 10 on the y-axis. A polygon P prime Q prime S prime R prime is shown with vertex P prime on ordered pair 3, 2, vertex Q prime on ordered pair 1, 2, vertex S prime on ordered pair 1, 1 and vertex R prime on ordered pair 2, 1. A polygon PQSR is shown with vertex P on ordered pair 9, 6, vertex Q on ordered pair 3, 6, vertex S on ordered pair 3, 3 and vertex R on ordered pair 6, 3. Which set of transformations was performed on PQSR to form P'Q'S'R'?
