Question

pentagon vwxyz is shown on the coordinate grid. a student reflected pentagon vwxyz across the x - axis to create pentagon vwxyz. which rule describes this transformation? (x,y) to (x,-y) (x,y) to (x,y + 8) (x,y) to (-y,x) (x,y) to (-x,y)

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: Identify the rule

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

Answer:

$(x,y)$ to $(x,-y)$
