Answer 1

Hello madison

Center of circle with the equation\[(x-a)^2+(y-b)^2=r^2\]is the point\[(a,b)\]so can you tell me which one of the options is right?

Answer 2

you should just find a and b for your equation

Answer 3

(2,-3)? @mukushla

Answer 4

look, you have\[(x+2)^2+(y-3)^2=25\]or\[(x-(-2))^2+(y-3)^2=5^2\]now compare this with general equation of a circle which I provided for you above

Answer 5

Come on, you can do it, its easy as pie for you

Answer 6

Its basically just the same. it just has the numbers plugged in @mukushla
