Two similar polygons are shown below:
a coordinate grid is shown from positive 6 to negative 6 on the x-axis and from positive 6 to negative 6 on the y-axis. a polygon pqrs is shown with vertex p on ordered pair negative 4, negative 2, vertex q on ordered pair negative 4, negative 6, vertex r on ordered pair negative 2, negative 4 and vertex s on ordered pair negative 2, negative 2. a polygon p prime q prime r prime s prime is shown with vertex p prime on ordered pair negative 2, negative 1, vertex q prime on ordered pair negative 2 , negative 3, vertex r prime on ordered pair negative 1, negative 2 and vertex s prime on ordered pair negative 1, negative 1.
which transformation was performed on pqrs to form p′q′r′s′?
a dilation factor of 2
a dilation factor of 4
a dilation factor of 1 over 2
a dilation factor of 1 over 4
