(x+3)^2+(y-5)^2=85

(x + 3)^{2} + (y - 5)^{2} = 85

(a, b) = (- 3, 5), r = 85

Solution steps

(x + 3)^{2} + (y - 5)^{2} = 85

Rewrite

(x + 3)^{2} + (y - 5)^{2} = 85

in the form of the standard circle equation

(x - (- 3))^{2} + (y - 5)^{2} = (85)^{2}

Therefore the circle properties are:

(a, b) = (- 3, 5), r = 85

(x - 5.5)^{2} + (y - 0.5)^{2} = 3.53

x^{2} + y^{2} - 20 x - 10 y = 5925

x^{2} - 1 x + y^{2} - 3 y - 20 = 0

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

16 = (x - 9)^{2} + (y + 4)^{2}
