x^2+y^2+4y-60=0

x^{2} + y^{2} + 4 y - 60 = 0

(a, b) = (0, - 2), r = 8

Solution steps

x^{2} + y^{2} + 4 y - 60 = 0

Rewrite

x^{2} + y^{2} + 4 y - 60 = 0

in the form of the standard circle equation

(x - 0)^{2} + (y - (- 2))^{2} = 8^{2}

Therefore the circle properties are:

(a, b) = (0, - 2), r = 8

y^{2} = - 28 x

f (x) = x^{2} + x - 6

36 x^{2} + 5 y^{2} - 90 y - 495 = 0

\frac{x ^{2}}{9} + \frac{y ^{2}}{5} = 1

x^{2} + 9 y^{2} = 9
