Question

the point u(-1, -3) is reflected over the x - axis. what are the coordinates of the resulting point, u?

Explanation:

Step1: Recall reflection rule

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

Step2: Apply rule to point U

For the point $U(-1,-3)$, the $x$-coordinate of the reflected point $U'$ is $x=-1$ and the $y$-coordinate of $U'$ is $y = -(-3)=3$.

Answer:

$(-1,3)$
