The centre of the circle x2+ y2 – 4x – 6y – 12 = 0 is
(-2 , 3)
(-2, -3)
(2,3)
(1,2)
The equation becomes -- (x−2)2+ (y−3)2 = 52
∴The centre of the circle x2+ y2 - 4x - 6y - 12 = 0 is (2, 3).
The diameters of a circle are along 2x+y−7=0 and x+3y−11=0 Then the equation of this circle, which also passes through (5,7) is
The equation of the circle passing through the points (4,1),(6,5) whose centre lies on the line 4x+y-16=0 is
