A polygon is shown on the graph: A polygon is shown on a coordinate plane. Vertex A is at 1 comma 5, vertex B is at 0 comma 1, vertex C is at 6 comma 1, and Vertex D is at 5 comma 5.

If the polygon is translated 2 units down and 4 units left, what will the coordinates of the new image be? Use prime notation in expressing the new coordinates. (5 points)
