Question

reflections over the x - axis change the sign of the _____________. x - coordinate x - axis y - axis y - coordinate

Explanation:

In a coordinate - plane, when a point is reflected over the x - axis, the x - coordinate remains the same and the sign of the y - coordinate changes. For example, the point $P(2,3)$ is reflected to $P'(2, - 3)$ over the x - axis.

Answer:

y - coordinate
