Reflection Coordinate Grid

Triangle ABC was transformed to create triangle A'B'C'. Which rule best describes this transformation?

Pentagon VWXYZ is shown on the coordinate grid. A student reflected pentagon VWXYZ across the x-axis to create pentagon V'W'X'Y'Z'.

• (x, y)

• (x, -y)

• (-x, y)

• (-x, -y)
