  • This is the standard form for a circle given its center and radius. You really need to review the basics, because you should be able to see the answer, (-9, 6), easily from that formula.

  • The center of a circle (x – a)^2 + (y – b)^2 = r^2 is (a,b). Compare to your equation.

    The radius is r.

  • (x+9)² + (y-6)² = 102

    center (-9, 6)

    radius = √102

  • (-9, 6)

    x: -9, y: 6

  • C (- 9 , 6 )

  • (-9, 6)

  • Exactly in the middle.

  • (x,y) = (-9,6)
