Graph (x+3)^2+(y-4)^2=16
Step 1
This is the form of a circle. Use this form to determine the center and radius of the circle.
Step 2
Match the values in this circle to those of the standard form. The variable represents the radius of the circle, represents the x-offset from the origin, and represents the y-offset from origin.
Step 3
The center of the circle is found at .
Center:
