You don't say what the actual problem is.
I see the resemblance to finding the equation of a circle??
What are you trying to find?

It says to write an equation of a circle with diameter
__
AB

Is A at (3,0) and B at (7,6) ?
if so then the center is halfway between.
Xc = (3+7)/2 = 5
Yc = (0+6)/3 = 3
so of form
(x  5)^2 + (y  3)^2 = r^2
but r is half the length of AB
AB^2 = 4^2 + 6^2 = 16+36 = 52
AB = 7.21
(1/2) AB = r = 3.61
r^2 = 13
so in the end
(x  5)^2 + (y  3)^2 = 13 
6 = x + 2
