Conic Sections Ellipse

What is the coordinates of the center and the radius of the circle with equation:

(x + 7)^2 + (y - 6)^2 = 64 ?

• Center (7,-6)

  Radius = 8 units

• Center (-7,6)

  Radius = 64 units

• Center (-7,6)

  Radius = 8 units

• Center (7,-6)

  Radius = 64 units

x + 3 = (y  - 1)²
