Question

(x, y) -------> (x, -y) is a reflection over the x axis. true false 10/30

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
