Answer is A” (-2, 7) B” (3, 6) C” (4, -2)
Step by step
The reflection of point (x, y) across the x-axis is (x, -y) so
A (2, -7) ➡️ A’ (2, 7)
B (-3, -6) ➡️ B’ (-3, 6)
C (-4, 2)➡️ C’ (-4, -2)
Then the rule for a reflection over the y -axis is (x,y)→(−x,y)
A’ (2, 7) ➡️ A” (-2, 7)
B’ (-3, 6) ➡️ B” (3, 6)
C’ (-4, -2) ➡️ C” (4, -2)
Problem solved!
