The center of circle (x-7)^2 + (y-2)^2 =100 is (-7,-2), True or false!!! THANKS

OpenStudy (amistre64):

youve got the right idea, but the wrong signs

OpenStudy (loser66):

@m74life my question is how do you get (-7, -2) I can see they are from the equation, but from which logic, you can pick it out to consider whether it's a center of circle or not? Please, explain me

OpenStudy (anonymous):

No its true or a false questions.

OpenStudy (loser66):

sure, but before consider whether it's true or false we have to know why we pick it but not other pair? for example, if I pick (0,0) i have to know how I get it, right?
