Find the standard form of the equation of the ellipse with the given characteristics.

vertices: (- 2, 2), (- 2, 16)
minor axis of length 8

Which equation represents a circle with a center at (–3, –5) and a radius of 6 units? (x – 3)2 + (y – 5)2 = 6 (x – 3)2 + (y – 5)2 = 36 (x + 3)2 + (y + 5)2 = 6 (x + 3)2 + (y + 5)2 = 36
