<u>Given</u>:
Line segment DM with end points D(-4,5) and M(6,0) is reflected about the x - axis to give line segment D'M'.
We need to determine the coordinates of the point D'.
<u>Coordinates of the point D':</u>
The general to reflect the coordinates over the x - axis is given by

To determine the coordinates of the point D', let us substitute the coordinates of the point D in the above rule.
Thus, we get;

The reflection of the coordinate D(-4,5) about the x - axis to give the point D' is (-4,-5)
Thus, the coordinates of the point D' is (-4,-5)
