Question

point a is the image of a under a reflection across the x - axis. find the coordinates of a. a(-5, -5) show your work here

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: Apply rule to point A

Given point $A(-5,-5)$, the $x$-coordinate of $A'$ is $x=-5$, and the $y$-coordinate of $A'$ is $y = -(-5)=5$.

Answer:

$A'(-5,5)$
