Question

quadrilateral wxyz is reflected across the x - axis. if (x,y) are the coordinates of one of its vertices, which ordered pair represents the reflected vertex? (-x,y) (-x,-y) (x,-y) (y,x)

Explanation:

Step1: Recall reflection rule

When reflecting a point $(x,y)$ across the $x - axis$, the $x$-coordinate remains the same and the sign of the $y$-coordinate changes.

Step2: Apply the rule

If the original point is $(x,y)$, the reflected point is $(x, - y)$.

Answer:

C. $(x, - y)$
