Damian dilates Triangle PQR shown on the coordinate plane with a scale factor of 0.5 centered at the origin. Then he translates the image 1 unit up and 3 units to the right to form Triangle P'Q'R'. What are the coordinates of the vertices of Triangle P'Q'R'?

• P' (0, 3), Q' (4, 5), R' (4, -1)

• P' (-3, 2), Q' (1, 4), R' (1, -2)

• P' (-6, 4), Q' (2, 8), R' (2, -4)

• P' (0, 2), Q' (4, 4), R' (4, -2)
