A 90° rotation counterclockwise will map every point (x, y) to (-y, x).
Looking at the pre-image and image points, we have:
P(-3, 5)→P'(-5, 3);
Q(-1, 3)→Q'(-3, -1);
R(-3, 1)→R'(-1, -3); and
S(-5, 3)→S'(-3, -5).
In each mapping, the x- and y-coordinate have been switched and the y-coordinate has been negated. This is the rule for a 90° counterclockwise rotation, so the correct choice is R0, 90°.
the answer is A i just took the test on ed
