The equation of a circle with center (h,k) and radius r is given by:
(x-h)^2 + (y-k)^2 = r^2
Substitute the given values into the equation:
(x-7)^2 + (y+1)^2 = 2^2
(x-7)^2 + (y+1)^2 = 4
Therefore, the equation of the circle is:
(x-7)^2 + (y+1)^2 = 4
Determine the equation of the circle graphed below.
Center : (7,-1)
Radius 2
