Two similar triangles are shown on the coordinate grid:
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 triangle PQR is shown with vertex P on ordered pair negative 4, 2, vertex Q on ordered pair 0, 0, and vertex R on ordered pair 2, 6. A triangle P prime Q prime R prime is also shown with vertex P prime on ordered pair negative 2 and negative 1, vertex Q prime on ordered pair 0 and 0 and vertex R prime on ordered pair 1 and negative 3.
Which set of transformations has been performed on triangle PQR to form triangle P′Q′R′? (5 points)
