Question

Find the image of (1,2) after a reflection about y=-1 followed by a reflection over y=1

Answer 1

(1, 6).

Explanation:

The reflection of the x coordinate of (1, 2) creates a point with y -coordinate

-1 - 3 = -4 while the x-coordinate remains 1.

The point (1, -4) is now reflected about y = 1, so -4 translates to 1 + 5 = 6. and x stays at 1.

Answer is (1, 6).
