Image below
(x, y) --> (x - 1, y + 4) and reflect across x = -1
(x, y) --> (x + 4, y -1) and reflect across x = -1
(x, y) --> (x - 1, y + 4) and reflect across y = -1
(x, y) --> (x + 4, y - 1) and reflect across y = -1

10. Which transformations result in a preimage and image with opposite orientations?
1 point
Dilations only
