Question

The general form of the equation of a circle is Ax2 + By2 + Cx + Dy + E = 0, where A = B 0. If the circle has a radius of 3 units and the center lies on the y-axis, which set of values of A, B, C, D, and E might correspond to the circle?

Answer 1

Here are my options

Answer 2

A = 0, B = 0, C = 2, D = 2, and E = 3

A = 1, B = 1, C = 8, D = 0, and E = 9

A = 1, B = 1, C = 0, D = -8, and E = 7

A = 1, B = 1, C = -8, D = 0, and E = 0

A = 1, B = 1, C = 8, D = 8, and E = 3
