Point R(8, 13) is translated 8 units left and 6 units down to create R’. a. Write a rule for the transformation.

• (x, y) → (x - 8, y - 6)

• (x, y) → (x + 8, y + 6)

• (x, y) → (x + 8, y - 6)

• (x, y) → (x - 8, y + 6)

Point R(8, 13) is translated 8 units left and 6 units down to create R’. b. Give the location of R’.

• R' = (0, 7)

• R' = (16, 19)

• R' = (8, 19)

• R' = (0, 19)
