Question

How to find the midpoint of a line segment with 2 given point?

Answer 1

If the 2 given points are endpoints, then we're in business.  The formula for the midpoint is $M=( \frac{ x_{1}+ x_{2} }{2}, \frac{ y_{1} + y_{2} }{2})$.  If the endpoints of our segment are the coordinates (1,2) and (12,14), our formula would be filled in as follows: $M=( \frac{1+12}{2}, \frac{2+14}{2})$ which simplifies to (13/2, 8).  See?  It's pretty simple once you know how to do it.
