How to Graph a Circle

1. Write the equation in standard form x² + y² = r²
2. Determine the center and graph it.
   • If the center is not (0,0), remember it's the (h,k) of (x - h)² + (y - k)² = r².
3. Determine the radius. 
4. Graph four points.
   • The distance from these four points to the center must be equal to the length of the radius.
5. Connect the points with a circle.
