Homework Statement
Find an equation of the circle passing through:
A(-3,1) with radius 2 and centre on the line 2x-3y+3=0
Homework Equations
x2+y2+2gx+2fy+c=0
r2=g2+f2-c
The Attempt at a Solution
using this equation , i have found 2 equations
-6g+2f+c=-10 by putting (-3,1)
-2g+3f+3=0 (-g,-f) in the linear equation which passes through the centre
how can i use radius information here to get the third equatio n ?
