Unit 4.1 Transformations

Given C(2, 9), under which reflection is C'(-2, 9)?

• reflected in the x-axis
• reflected in the y-axis
• reflected in the line x = 2
• reflected in the line y = x

• F
• G
• H
• J

Write a rule for the translation.

•  (x -1, y  + 2)
•  (x -2, y  + 1)
•  (x +2, y  - 1)
• (x +1, y  -  2)

Identify the transformation.

• Reflection across y axis
• Reflection across x-axis
• 180 Rotation
• Translation 2 units down
