You can put this solution on YOUR website! Equation of a circle Passing through (6,-1) and tangent 4y-3x-2=0 at (2,2)
--------
A(6,-1) and B(2,2) are 2 points on the circle.
-----------
Find the equation on the line thru (2,2) and perpendicular to the line 4y-3x-2=0.
The center of the circle is on that line.
---
Find the perpendicular bisector of AB.
The center of the circle is on that line.
---------
The intersection of the 2 lines is the center.
The distance from the center to either point is the radius.
