Question

What is the standard form of the equation of the circle in the graph?

(x + 3)2 + (y - 1)2 = 2
(x - 3)2 + (y + 1)2 = 1
(x - 3)2 + (y + 1)2 = 2
(x + 3)2 + (y - 1)2 = 1

Answer 1

Answer 2

First thing, we need to look at how the standard form of a circle looks and then compare it to the options. Just a sec.

Answer 3

Look at the attachment and let's compare that to the options.

Any idea which one it might be?

Answer 4

I just saw the circle diagram. Do you get (-3, 1) for the center?

Answer 5

And, with a radius of 1?

Answer 6

So, (x - (-3)) ^2 + (y - 1) ^2 = 1^2

(x + 3)^2 + (y - 1) ^2 = 1

@Saylilbaby Do any of the options look like that?
