First, let's find the coordinates of point P.

Looking at the graph, point P is located at (-5, 3).

The expression Ry=-1(P) means point P will be reflected over the line y = -1.

To find the coordinates of the image, let's find the distance from point P to the line y = -1.

The y-coordinate of point P is 3, so the distance from point P to the line y = -1 is 4 units (from 3 to -1).

Then, to find the y-coordinate of the image, let's decrease 4 more units from y = -1. Therefore the new y-coordinate is -5.

So the image is located at (-5, -5).
