When you translate, (x, y) → (x-4,y) will move _________.

• 4 units right
• 4 units left
• 4 units up

When you reflect a shape, you ______ over an axis or line.

• Flip
• Rotate
• Slide
• Expand

Write a rule for the translation.

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