Question

pq is reflected across the y - axis to produce pq

1. write the rule for the reflection.

(x,y)→( )

Explanation:

Step1: Recall reflection rule

When reflecting a point $(x,y)$ 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:

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