Reflections
Reflect (2, 3) over the x-axis
What is (2, -3)
Rotate (2, 3) 90 degrees clockwise
What is (3, -2)
(2,3) moves 2 units right
What is (4, 3)

What is Translation
Reflect (-3, 2) over the x-axis
What is (-3, -2)
Rotate (-3, 2) 90 degrees counter clockwise
What is (-2, -3)
(2, 3) moves 4 units up
