(X+7)^2+(y-1)^2=9

(X + 7)^{2} + (y - 1)^{2} = 9

(a, b) = (- 7, 1), r = 3

Solution steps

(X + 7)^{2} + (y - 1)^{2} = 9

Rewrite

(X + 7)^{2} + (y - 1)^{2} = 9

in the form of the standard circle equation

(X - (- 7))^{2} + (y - 1)^{2} = 3^{2}

Therefore the circle properties are:

(a, b) = (- 7, 1), r = 3

(x^{2} - 2) + (y^{2} + 4) = 4

(x - 3)^{2} + (y + 1)^{2} = 49

(x + 7)^{2} + (y - 6)^{2} = 361

(x + 4)^{(2)} + (y - 2)^{(2)} = 25

\frac{x ^{2}}{6 ^{2}} + \frac{y ^{2}}{6 ^{2}} = 1
