C(-6, 2) and B(-1, -1)
Reflect over the line y = x

• C' (-6, 2), B' (-1, -1)
• C' (6, 2), B' (1, -1)
• C' (2, -6), B' (-1, -1)
• C' (-6, -2), B' (-1, -1)

A(-2, 2) and B(3, 2)
Reflect over the x-axis 

• A' (-2, 2), B' (3, 2)
• A' (-2, -2), B' (3, -2)
• A' (2, -2), B' (-3, -2)
• A' (2, -2), B' (2, 3)

C(-6, 2) and B(-1, -1)
