Answer:
(a) (x -6, y -2)
Step-by-step explanation:
You seem to want to see the inverse of the translation T, applied twice. Your notation seems to mean ...
For T = (x, y) +(a, b)
T⁻¹ = (x, y) -(a, b) ⇒ T⁻² = (x, y) -2(a, b)
__
Your given transformation is ...
T = (x, y) +(3, 1)
which means ...
T⁻² = (x, y) -2(a, b) = (x, y) -2(3, 1)
T ⁻² = (x -6, y -2)
