I need help with Geometry

Question

If the point R(-2,4) what would r be reflected over the x axis?

Answer 1

then y changes sign, so (-2,-4)

Answer 2

When a point is reflected over the x-axis the point maintains it distance from the x-axis but on the other side, i.e., the y-coordinate is negated: (-2,4) becomes R'(-2,-4).
