Wait but I dont see a circle. Find the radius of what?

seriously though I just finished pre algebra and this stuff looks creepy as forget.


I pitty da foo who deals with this kinda math on a daily basis

It's a graphing coordinate for a circle.

X and Y squared in graphing land has to do with a curve.

x^2+y^2-12x+4y+31=0

(x^2 - 12x) + (y^2 + 4y) = -31
(x^2 - 12x + 36) + (y^2 + 4y + 4) = - 31 + 36 + 4
(x - 6)^2 + (y + 2)^2 = 9

radius is 3
