1. Circles A review?

2. Let's review what we already know about circles. Definition: A circle is a locus (set) of points in a plane equidistant from a fixed point.

3. General Equation of a Circle Circle whose center is at (h,k) (This will be referred to as the "center- radius form". It may also be referred to as "standard form".)

4. Review Again Write the equation of a circle whose diameter has endpoints (4, -1) and (-6, 7).

5. Review Again Write the equation of a circle whose diameter has endpoints (4, -1) and (-6, 7).

6. Review Again Write the equation for the circle from the origin if it is shifted 3 units to the right and 4 units up with a radius of 4.
