Question

point q is the image of q under a reflection across the y - axis. find the coordinates of q. q(12,17)

Explanation:

Step1: Recall reflection rule

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

Step2: Apply the rule

For point $Q(12,17)$, $x = 12$ and $y=17$. After reflection across the $y - axis$, the $x$-coordinate changes sign and the $y$-coordinate remains the same. So the new $x$-coordinate is $- 12$ and $y$-coordinate is $17$.

Answer:

$Q'(-12,17)$
