If square abcd is defined by the coordinates a(0, 0), b(0, -5), c(-5, -5), d(-5, 0) is dilated by a scale factor of 2, with resulting vertex a' at (5, 5). what is the center of the dilation?

Lena reflected this figure across the x-axis. she writes the vertices of the image as a'(−2, 8), b'(−5, 6), c'(−8, 8), d'(−4, 2).
