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 the x-axis.
The line of reflection is the x -axis.

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

The line of reflection is horizontal.
The line of reflection is horizontal.

The line of reflection is the y-axis.

Answer 1

If points T and T′ have the same x-coordinate after point T is reflected over a line of reflection, this means that the line of reflection must be horizontal. This is because a horizontal line of reflection will only change the y-coordinates of the points, while keeping their x-coordinates the same.

Therefore, the correct response is:

The line of reflection is horizontal.
