Answer 2

do you know the circle equation?

Answer 3

They keep beating me grr

Answer 4

yeah one sec i have it in my notes

Answer 5

(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius

Answer 6

Here are your answers now for the work :)
Center:: (-2,3)
Radius:: (3)

Answer 7

@gaos finish what you started :)

Answer 8

OK so wanna plug them in with me?

Answer 9

(x^2+4x+4)-4+(y^2-6y+9)-9=-4
(x+2)^2+(y-3)^2=9
(x+2)^2+(y-3)^2=3^2
Circles follow the form: (x-a)+(y-b)=r^2
Therefore the center of the circle is at (-2,3) and the radius is 3.
