(x-3)^2+(y+2)^2=9
Change the sign of the -3 to +3, or just 3
Change the sign of the +2 to -2.
Put those numbers in an ordered pair like this:
(3,-2)
That's the center of the circle
Plot it
Now take the square root of the 9 on the right side of
the given equation,
(x-3)^2+(y+2)^2=9
and get 3.
That is the radius of the circle. So open your compass
so that it is 3 units between the sharp point and the pencil.
Put the sharp point on the center (3,-2) and draw the circle:
That's the graph of
(x-3)^2+(y+2)^2=9
