Question

Quadrilateral A B C D has vertices at A negative two comma negative one, B negative four comma negative seven, C negative nine comma negative three and D negative eight comma negative six. It is reflected across the x-axis. What are the new coordinates? Explain.

Answer 1

reflecting across the x-axis changes the sign of the y-values.

Answer 2

When a point is reflected through the x-axis, the x-coordinate stays the same, and the y-coordinate changes sign.
