In words:
( endpoint #1 + endpoint #2) / 2 = midpoint
You need to use this formula twice, once for
x-coordinates, and again for the y -coordinates
----------------------------------
suppose the endpoints are:
(0,1) and (7,5)
(7 + 0)/2 = 7/2
and
(5 + 1)/2 = 3
The midpoint is (7/2 , 3)
--------------------
To check, the equation that includes the endpoints is

Does it include the midpoint?

OK
