• (-1,6)

• (5,6)

• (7,-1)

• Right 6 and Up 2

• Right 5 and Down 8

• Left 5 and Down 5

Write the rule that describes the transformation.

• (x,y) ⟶ (x + 4, y – 6 )

• (x,y) ⟶ (x – 6, y + 6)

• (x,y) ⟶ (x + 2, y – 4)

• (x,y) ⟶ (x + 6, y – 4)

True or false. A translation is a rigid motion.

• True

• False

Given 𝛥𝑋𝑌𝑍, what is the rule to describe the translation if X (-2, 3) is translated to X’ (1, -2) ?

• (x,y) ⟶ (x +1, y – 1)
