Graphing circles worksheet for Algebra 2
The equation of a circle already tells you the two things you need: where the center is and how far out to go. A grid comes with every question and the answer key has the circle drawn on it.
Also taught in Precalculus, at its own level and with its own examples.

How to do these
Graph
- The center is at (2, -1): the values that make each squared binomial zero.
- The right side is the radius squared, so the radius is 3.
- Mark the center, step 3 out in all four directions, and join them.
The answer is Center , radius .
Where students go wrong
Taking the right side as the radius. It is the radius squared, so 9 means a radius of 3, not 9. The other slip is reading the center with the wrong sign: (x - 2) puts the center at +2.
Also called plotting circles or center and radius graphs.
