Question

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

Explanation:

Step1: Recall reflection rule

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

Step2: Write the rule

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

Answer:

$(-x,y)$
