Implicit Equations

[1141]

I need some help on a question:

"Find the coordinates of the center -

x[sup:35f3aojl]2[/sup:35f3aojl] + y[sup:35f3aojl]2[/sup:35f3aojl] = 25
(-3;4)"

I'm not sure what I'm supposed to do to start the question, and the example that the book tells me to look at if I'm stuck, really doesn't help me at all.

\(\displaystyle x^2+y^2 \ = \ 25 \ is \ a \ circle \ with \ center \ at \ (0,0) \ and \ radius \ 5, \ see \ graph.\)

(-3;4)"

Do you know why this is given ?

I don't.

Re:

I don't.

Um, I think those are the co-ordinates of the point on the circumference of the circle.
If it makes anything clearer, attached is the example I'm told to look at the help solve the equation.

No, that doesn't help explaining why (-3,4) is given...

Why don't you Google "introduction to circle equation" and see what you can learn...BEST WAY!!
