The coordinates of a quadrilateral are , , , and . Quadrilateral ABCD is reflected across the x-axis to create quadrilateral A’B’C’D’.

What is the rule that describes this transformation?

1 answer

The rule for reflecting a point across the x-axis is to change the sign of the y-coordinate while keeping the x-coordinate the same.

Therefore, the coordinates of A'B'C'D' would be (-3, -5), (-1, 2), (3, 6), (4, 1).
