Answer:
[tex](x+2)^2 + (y-1)^2 = 9[/tex]
Step-by-step explanation:
The equation of a circle is written with the center and radius into the vertex form [tex](x-h)^2 + (y-k)^2 = r^2[/tex].
Here h = -2 and k = 1. Substitute these values with r = 3.
[tex](x--2)^2 + (y-1)^2 = 3^2\\(x+2)^2 + (y-1)^2 = 9[/tex]
