Question

When I calculated it I got A.
It's confusing though because I've never seen the equation of a circle with two + signs.

Answer 1

So you're not 100% sure it's A?

What calculations do you have so far?

Answer 2

I did the calculations twice, even calculated option A. 3 times ; it is correct.

Answer 3

As the coordinates of the center of the circle is negative, you get two positive signs.

Answer 4

^Thank you for clarifying that :)
