Question

please check my answer
What is the standard form of the equation of the circle in the graph?

(x + 1)2 + (y + 2)2 = 16
(x - 1)2 + (y - 2)2 = 16
(x - 1)2 + (y - 2)2 = 4 my answer
(x + 1)2 + (y + 2)2 = 4

Answer 1

it should be 16 on the right

Answer 2

oh yeah!

Answer 3

would it b B then?

Answer 4
