Question

(x, y) -------> (x, -y) is a reflection over the x axis. true false 23/30

Explanation:

Step1: Recall reflection rule

In a coordinate - plane, when a point $(x,y)$ is reflected over the x - axis, the x - coordinate remains the same and the y - coordinate changes its sign. So the image of the point $(x,y)$ after reflection over the x - axis is $(x, - y)$.

Answer:

True
