Unit 1 Transformations in the Coordinate Plane

Translations

Translate (x – 9, y + 8) C’ (-18, 20)  O’ (-21, 4)  W’ (13, -11)

Translate (x + 1, y – 6) A’ (-3, -2)   B’ (4, -5)  

Reflections

Reflect across the x-axis Change the sign of the y-value

Reflect across the x-axis

Reflect across the x-axis   B’ (3, -1)  

Reflect across the y-axis Change the sign of the x-value

Reflect across the y-axis

Reflect across y = x Swap x and y

Reflect across y = x

Reflect across y = -x Swap and change both signs

Reflect across y = -x
