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)

Question

Responses

The line of reflection is vertical.
The line of reflection is vertical.

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.

Answer 1

If points T and T′ have the same x-coordinate after reflecting T over a line of reflection, it means that the line of reflection is horizontal. This is because a horizontal line of reflection will keep the x-coordinates the same while changing the y-coordinates.

So, the correct response is:

The line of reflection is horizontal.
