Answer:

B. (x, y) ⇒ (x, -y)

Explanation:

When a point is reflected over the x-axis, it is moved along a vertical line to the same distance on the other side of the x-axis.

The x-coordinate of a point identifies its distance from the y-axis--the vertical line it is on. The y-coordinate identifies its distance from the x-axis. Changing the sign of the y-coordinate moves the point to the same distance on the other side of the x-axis--reflecting it over the x-axis.

__

The given points ABC and A'B'C' all match the pattern ...

(x, y) ⇒ (x, -y)

A(-1, 7) ⇒ A'(-1, -7)

B(6, 5) ⇒ B'(6, -5)

C(-2, 2) ⇒ C'(-2, -2)

so the image points represent a reflection over the x-axis of the original points.
