Question

Look at the graph.



Which equation best represents the circle in the graph?

Answer 1

(x - 2)2 + (y - 3)2 = 16
(x + 2)2 + (y - 3)2 = 16
(x - 2)2 + (y + 3)2 = 16
(x + 2)2 + (y + 3)2 = 16

Answer 2

A circle's equation is given as
\[(x-a)^2+(y-b)^2=r^2\]
where (a, b) is the center of the circle and r is the radius of the circle.
Now from the graph, find (a, b) and radius r and you'll get the answer. Count the blocks:)

Answer 3

So it's the first one?
