Question 706690
the circle passes through the points A(-5,2) and B(-1,4) and tangent to the line x-5y=10.
1. radius of the circle
2. equation of a circle in a center-radius form
3. equation of circle in general form
==================================
Find the eqn of the perpendicular bisector of the line thru A & B.  The center is on that line.
----
The intersection of the perp bisector and x-5y=10 is a point on the circle, point C.
Find the perp bisector of AC.
The intersection of the 2 perp bisectors is the center.
---
The radius is the distance from the center to A, B or C.
