Use the diagram to select the answer choice with the letter of the correct image described. Figure ___ is the result of the sequence: G reflected over a vertical line and then a horizontal line.

• B

• A

• C

• D

Look at the figures below. Which coordinate notation describes the transformation in the graph above?

• (x, y) → (0.5x, 0.5y) → (x − 3, y + 2)

• (x, y) → (2x, 2y) → (x + 3, y − 2)

• (x, y) → (0.5x, 0.5y) → (x + 3, y − 2)

• (x, y) → (2x, 2y) → (x − 3, y + 2)

Look at the figure below. Determine which statements is true.
