To reflect a point over the x-axis you have to reverse the sing of the y-coordinate leaving the y-coordinate of the point the same.

For example if you have the point P with coordinates (x,y) the reflection over the x-axis will be:

Original point → Reflection over x-axis

P(x,y) → P'(x,-y)

So for the point (6,-3) the reflection over the x-axis is:

(6,-3) → (6,-(-3)) = (6,3)
