11. Find the equation of the circle passing through the points (2,3) and (–1,1) and hose centre is on the line .
As we know,
The equation of the circle with centre ( h, k) and radius r is given by ;
Condition 1: the circle passes through points (2,3) and (–1,1)
Now, Condition 2: centre is on the line.
From condition 1 and condition 2
Now let's substitute this value of h and k in condition 1 to find out
So now, the Final Equation of the circle is
