    The equation of a circle with center (h,k) and radius r is given by:

    (x – h)^2 + (y – k)^2 = r^2

    So, for a circle with center (-3,1), the equation would be:

    (x – (-3))^2 + (y – 1)^2 = r^2

    Simplifying this, we get:

    (x + 3)^2 + (y – 1)^2 = r^2

    Note that we still need to know the radius of the circle in order to have a complete equation. Without more information about the circle, we cannot determine the value of r.
