Rigid Transformation Reflection

Is the picture being reflected in the y-axis or x-axis?

• y-axis

• x-axis

Reflecting over the y-axis changes the ____-_____________. 

• x-axis

• x-coordinate

• y-coordinate

• y-axis

What is the Algebraic Notation for this Reflection?

• (x, y) → (y, x)

• (x, y) → (-x, y)

• (x, y) → (-y, -x)

• (x, y) → (x, -y)
