Question

xy is reflected across the y - axis to create xy. what are the endpoints of xy?

Explanation:

Step1: Recall reflection rule

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

Step2: Find new coordinates of X

For point $X(3,5)$, applying the rule $(-x,y)$, we get $X'(- 3,5)$.

Step3: Find new coordinates of Y

For point $Y(2,7)$, applying the rule $(-x,y)$, we get $Y'(-2,7)$.

Answer:

The endpoints of $\overline{X'Y'}$ are $X'(-3,5)$ and $Y'(-2,7)$
