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'? a dilation factor of 2 a dilation factor of 1 over 3 a dilation factor of 1 over 2 a dilation factor of 3
