Andrea has to find a third point C to form a triangle on the coordinate plane shown. She is told the coordinates of this reflection point C across the X axis are two -2 what are the coordinates of C
If the x-coordinate of the reflection point C across the x-axis is 2, this means that the x-coordinate of the original point is also 2, but with a different sign. Since C is a reflection across the x-axis, the y-coordinate of the reflection point should be the opposite of the y-coordinate of the original point.
If the y-coordinate of the reflection point C across the x-axis is -2, this means that the y-coordinate of the original point is also -2, but with a different sign.
Therefore, the coordinates of point C are (2, -2).
