Transformations on the Coordinate Plane

What is the sequence of transformations?

• Reflect over the y then reflect over the x

• Reflect over the x then reflect over the y

• Translate 4 units then rotate 90˚

• Rotate 90˚ then reflect over the x

Which coordinate notation correctly describes a transformation that maps the black triangle to the gray triangle?

• The rotation (x, y) → (-x, -y)

• The translation (x, y) → (x + 6, y - 2)

• The rotation (x, y) → (-y, -x)
