If the of the circle passing through the points (3,4),(3,2),(1,4) is x^{2}+y^{2}+2ax+2by+c=0, then the ascending order of a, b, c is

(1, 2) is a point on the circle x^{2}+y^{2}+2x-6y+5=0 which is orthogonal to x^{2}+y^{2}=5. The conjugate point of (1, 2) w. r. to the circle x^{2}+y^{2 }=5 and which lies on the first circle is

Let C_{1}=x^{2}+y^{2}-2x-4y=0, C_{2}=x^{2}+y^{2}+2x+10y=0 and L=2x+7y+7=0 Then L is the

The equation of the circle having centre on the line x+y=1 and touching the lines 3x-4y+2=0, 4x+3y+7= 0 is

The equation of the circle passing through the points (4, 1), (6, 5) and having the centre on line 4x+y-16=0 is
