Learn the Distance Formula. This is simply an arrangement based on the Pythagorean Right Triangle theorem formula.

Pythagorean Theorem also gives a formula for equation of a circle.

In the example you asked, %28x-5%29%5E2%2B%28y-5%29%5E2=12%5E2.

-------------------
%28x-5%29%5E2+%2B+%28y-5%29%5E2+=+12%5E2 is the circle
You can solve for y
%28y-5%29%5E2+=+144+-+%28x-5%29%5E2
%28y-5%29+=+sqrt%28144+-+%28x-5%29%5E2%29
y+=+5+%2B+sqrt%28144+-+%28x-5%29%5E2%29
-----
Use the +sqrt for 1/2, then the -sqrt for the other half.
