Question

If the domain (or pre-image) is (-4, -2), (5, 9), (-6, 2) and the range (or image) is

Answer 1

Answer:  90 degrees clockwise

This is equivalent to 270 degrees counterclockwise

The rule for either rotation is $(x,y) \to (y,-x)$

The x and y coordinates swap places, and the new second coordinate flips from positive to negative (or vice versa).

The diagram below shows an example of this for the point (-4,-2) rotating to (-2, 4). The center of the rotation is the origin (0,0).
