9514 1404 393

Answer:

• A'(-2, -7)
• B'(4, -6)
• C'(-1, -1)

Step-by-step explanation:

Each image point is as far below the x-axis as the original point is above the x-axis. The original and its image are on the same vertical line.

If the vertices of the given triangle are A(-2, 7), B(4, 6), C(-1, 1), then the image points are ...

• A'(-2, -7)
• B'(4, -6)
• C'(-1, -1)

The reflection changes the sign of the y-coordinate.
