Circles: Equations




        Write an equation for each circle.

        7. a circle with center at (8, 4) and a radius with endpoint (0, 4)









        8. a circle with center at (–2, –7) and a radius with endpoint (0, 7)









        9. a circle with center at (–3, 9) and a radius with endpoint (1, 9)










        10. a circle whose diameter has endpoints (–3, 0) and (3, 0)










         Graph each equation.

        11. x² + y² = 16                                   12. . (x – 1)² + ( y – 4)² = 9
