1. 1. Circles
2. 2. Circle:   the set of points ( x , y ) that are  equidistant from a fixed point called the  centre of the circle.  Radius:  the distance between the centre of  the circle and any point ( x , y ) on  the circle
3. 3. y x
4. 4. Equation of a circle with centre at the origin:
5. 5. y Equation?  x
6. 6. Equation for parabola:  What does "h" do to the standard parabola?  What does "k" do to the standard parabola?
7. 7. The standard form for equation of a circle:  where ( h, k ) is the centre and r is the radius
8. 8. Second form for circle equation:  where d, e, and f are real numbers and  completing the square of this equation will  convert it into standard form.
9. 9. Convert to standard form then graph:
10. 10. y x
11. 11. Exercise 21 Questions 1 ­ 7
