Look at the graph.

which equation best represents the circle in the graph?

(x + 1)2 + (y - 4)2 = 9

(x + 1)2 + (y + 4)2 = 9

(x - 1)2 + (y - 4)2 = 9

(x - 1)2 + (y + 4)2 = 9

Assuming the 2's after the parentheses are squares, the answer would be the third option. The equation for a circle is (x – h)^2 + (y – k)^2 = r^2. Since it is in quadrant 1, there does not need to be any sort of sign changes for either x or y.
