x^2+y^2-6x+2y+9=0

x^{2} + y^{2} - 6 x + 2 y + 9 = 0

(a, b) = (3, - 1), r = 1

Solution steps

x^{2} + y^{2} - 6 x + 2 y + 9 = 0

Rewrite

x^{2} + y^{2} - 6 x + 2 y + 9 = 0

in the form of the standard circle equation

(x - 3)^{2} + (y - (- 1))^{2} = 1^{2}

Therefore the circle properties are:

(a, b) = (3, - 1), r = 1

4 x^{2} + y^{2} = 16

y = x^{2} - 24 x - 12

x = 4 y^{2}

\frac{x ^{2}}{36} + \frac{y ^{2}}{49} = 1

y^{2} = - 6 x
