Answer:

[tex](x-1)^{2} + (y+1)^{2} = 25[/tex]

Step-by-step explanation:

The radius of the circle is found my the y-axis,

We have the points at y=-1 and y=-6 subtracting them from would give us -5.

(-5)^2 = 25

The formula of the circle is [tex](x-a)^{2} + (y-b)^{2} = r^2 \\[/tex]

a and b are given, they are the center of the circle. so substituting them above would give us the answer.

Hope this helps.
