Translations and Reflections Review

Front

What is the Algebraic Notation for a reflection across the x-axis?

Back

(x, y) → (x, -y)

Front

What is the result of the translation (x, y) → (x + 3, y + 1) if the original point is (2, 1)?

Back

(5, 2)

If a figure is reflected over the x-axis, what happens to the y-coordinates of its points?

Back

The y-coordinates change sign.
