Find the center-radius form for the circle having the endpoints (7,2) and (-9,8) of a diameter.
---------------
The center is the midpoint.
Find the average of x & y separately for the midpoint.
x = (7-9)/2 = -1
y = (2+8)/2 = 5
--> center at (-1,5)
--------------
r is the distance from the midpoint to either point.
