Answer:

[tex](x-1)^2 + (y+4)^2=2^2[/tex]

Step-by-step explanation:

The equation of a circle is given by:

[tex](x-a)^2 + (y-b)^2 = r^2[/tex]

Where the center is (a,b) and the radius is r

Since center (1, -4), we can say :

[tex](x-a)^2 + (y-b)^2\\(x-1)^2 + (y+4)^2[/tex]

The right side would be  [tex]2^2[/tex]

So the equation woud be:  [tex](x-1)^2 + (y+4)^2=2^2[/tex]

This is the equation of the circle, posted.
