Apply geometric motions to reflect figures. Brinda reflects point T over a line of reflection, resulting in point T′ . If points T and T′ have the same x-coordinate, what must be true?(1 point) Responses The line of reflection is the x-axis. The line of reflection is the x -axis. The line of reflection is the y-axis. The line of reflection is the y -axis. The line of reflection is horizontal. The line of reflection is horizontal. The line of reflection is vertical. The line of reflection is vertical.

Answer 1

If point T and its reflection point T′ have the same x-coordinate, it means that they must lie on a vertical line of reflection. Therefore, the line of reflection must be vertical, which typically means it is the y-axis or another vertical line. The correct response is:

The line of reflection is vertical.
