Question 293930
To move left (negative x), add to x term.
To move up (positive y), subtract from y term.
--> (x+2)^2 + (y-4)^2 = 16
---------------------------
The general equation of a circle is (x-h)^2 + y-k)^2 = r^2 where (h,k) is the center.
---------
Your original eqn was (x-0)^2 + y-0)^2 = r^2
To move the center to (-2,4), make the changes to h and k.
