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 at (0, 4), which set of values of A, B, C, D, and E correspond to the circle?
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

Answer 1

PLEASE HELP

Answer 2

\[\large\rm (x-x_1)^2+(y-y_1)^2 =r^2 \]

Answer 3

and (x1,y1) are the centre of the circle
