X DISTANCE=(3+1)=4 SO WE SUBTRACT 4 FROM P=-4-4=-5
Y DISTANCE=9-5)=4 SO WE SUBTRACT 4 FROM P=5-4=1
NOW WE HAVE THE END POINT (-5,1)

Find the coordinates of the missing endpoint given that P is the midpoint of NQ.
Q (3,9) P(-1,5)
---------------------
Let the other end point be (x,y)
----------------
Note: The coordinates of the midpoint are the average of the coordinates of
the endpoints.
---------------------
EQUATIONS:
(3+x)/2 = -1
3+x=-2
x=-5
---------
(9+y)/2 = 5
9+y = 10
y = 1
--------------
Coordinates of the other end point (-5,1)
