Question

quadrilateral qrst is reflected across the x - axis to produce quadrilateral qrst. write the rule for the reflection. (x, y)→( , )

Explanation:

Step1: Recall reflection rule

When reflecting a point $(x,y)$ across the $x - axis$, the $x$-coordinate remains the same and the $y$-coordinate changes its sign.

Step2: Write the rule

The rule for reflecting a point $(x,y)$ across the $x - axis$ is $(x,y)\to(x, - y)$.

Answer:

$(x,y)\to(x, - y)$
