What is the standard form of equation of a circle with center at (-2, -3) and passing through the point (-2, 0)? A) (x + 2)2 + (y + 3)2 = 9 B) (x − 2)2 + (y − 3)2 = 16 C) (x − 2)2 + (y − 3)2 = 4 D) (x + 2)2 + (y + 3)2 = 16 E) (x − 2)2 + (y + 3)2 = 9

    Standard circle - (x - h)^2 + (y - k)^2 = r^2 the center is point (h,k) and radius r

    The radius here is the distance from center point to the other point on the circle

    (x-2)^2+(y-3)^2 is the equation i use?

    Careful with that, the center point has both negative values for h and k, minus a negative is addition
