What are the coordinates of A (1, 2), B (3, 4), and C (5, 6) after a reflection over the x-axis?

When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite, i.e. it changes the sign.

Let's start with the point A(1,2)

The reflection of this point is found by keeping the x-coordinate, and changing the sign of the y-coordinate, that is, the new point A' is

A'(1,-2)

Apply the same with point B:

B=(3,4) -> B'=(3,-4)

Finally, for point C:

C=(5,6) => C'=(5,-6)
