The points A(8,4) is on the circle that is tangent to the line 3y-4x-11=0
at B(1,5). Find the equation of the circle. Where does it cut the x-axis?
-------------
Find the PB (perpendicular bisector) of AB.
The center of the circle is on that line.
----
Find the equation of the line perpendicular to the given line thru B.
The center of the circle is on that line.
==============
Find the intersection of the 2 lines --> center C (h,k).
========
The radius r is the distance AC or BC.
==================
%28x-h%29%5E2+%2B+%28y-k%29%5E2+=+r%5E2
