1. What is the center of the circle given by the equation (x + 5)2 + y2 = 16?
2. What is the center of the circle x2 + y2 - 8y + 1 = 0?
3. What is the equation, in general form, of the circle whose center is (1, 2) and which contains the point (1, -1)?
ok, hes what i got.
on #1 i am just stuck
on #2 i narrowed down the equation to (x2)+(y-4)=-1 or so thats what i think but after that i am stuck
on #3 i have no idea.
can anyone help me get through these? thanks
