# How to Find the Midpoint of a Line Segment

The middle of a line segment is its *midpoint.** *To find the midpoint of a line segment, you just calculate the averages of the coordinates — easy as pie.

The midpoint, *M*, of a segment with endpoints (*x*_{1},*y*_{1}) and (*x*_{2},*y*_{2}) is

If you want to know the midpoint of the segment with endpoints (–4,–1) and (2,5), then plug the numbers into the midpoint formula, and you get a midpoint of (–1,2):

See how this segment looks in graph form in the following figure.
