Andrea has to find a 3rd point, C, to form a triangle on the coordinate plane shown. She is told the coordinates of the reflection points, C’, across the x-axis are (2, -2) What are the coordinates of point C?

Answer 1

To find point C, we need to reflect point C' across the x-axis.

When a point is reflected across the x-axis, the x-coordinate remains the same, while the y-coordinate changes sign.

Therefore, the coordinates of point C are (2, 2).
