x^2+y^2+8x-6y=6

x^{2} + y^{2} + 8 x - 6 y = 6

(a, b) = (- 4, 3), r = 31

Solution steps

x^{2} + y^{2} + 8 x - 6 y = 6

Rewrite

x^{2} + y^{2} + 8 x - 6 y = 6

in the form of the standard circle equation

(x - (- 4))^{2} + (y - 3)^{2} = (31)^{2}

Therefore the circle properties are:

(a, b) = (- 4, 3), r = 31

x^{2} - 8 x + y^{2} - 2 y - 19 = 0

(x + 5)^{2} + (y + 0.6666600000000 \dots)^{2} = 0.4444400000000 \dots

x^{2} + y^{2} = 19.4 x + 3 y - 4

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

(x - 6)^{2} + (y - 4)^{2} = 16
