Answer:
(8, 0)
Explanation:
TAKE NOTE: In a glide reflection, you always start w/ the second transformation.
STEP 1: (2, 7) affected by the reflection
RULE (in this case): (x, y) --> (y, x)
(2, 7) => (7, 2)
STEP 2: (7, 2) affected by the translation
RULE: (x, y) --> (x + horizontal shift, y + vertical shift)
(7, 2) => (7+1, 2-2) or (8, 0)
You can check your answer by doing this the opposite way.
Hope this helped ^^
