Answer: the last one, (-1, 1), (7, 1), (3, 5)
Step-by-step explanation: If you take point A and move it 7 units to the right, A' would be (-1, 1) because the y-value does not change, and the x-value was previously at -8.
None of the other answers have (-1, 1) as A' except the last one, so by the process of elimination, the last one, or answer D, is correct.
