Please help!
A circle has its center at (-2, -3) and a radius of 3 units. What is the equation of the circle?

(x + 2)2 + (y + 3)2= 9

(x + 2)2 + (y - 3)2= 9

Answer 1

(x - 2)2 + (y - 3)2 = 3

(x + 2)2 + (y + 3)2 = 3

Answer 3

you're given the (h, k) values ALREADY, and the radius too, so just plug them in, in the circle equatioin
