Remember that a midpoint of a line segment is the point that divides the segment into two segments of equal length. On graph paper, plot the points and

*. Where is the midpoint*

*if*

*? Explain how you found your answer.*

*7-29 HW eTool*(Desmos) Homework Help ✎

Plot the points at their given coordinates.

Divide the length by two in order to find the length of and

*.*

To find the coordinates of the midpoint, take the coordinates of either Point *P* or Point *Q* and add or subtract, respectively, the length of *PM* and *MQ* to the -value.

Check your answer by placing the point at the coordinates you found.

Because the -values of the two points are the same, the length of the segment is equal to the difference between the

*-values of the two points.*
