Find image of (-15,13) for a dilation with the center (-1,-9) and a scale factor of 1/4.
We are stuck on these problems, and are having a tough time finding a way to solve with the resources we have. Any help would be very much appreciated.

Use similar triangles. All distances can be calculated by the coordinates of the 2 points.
Alternatively, first do a translation of (1,9), apply a dilation of 1⁄4 with the origin as the centre, then translate back to (−1,−9). So
