$a(x-{x}_{0}{)}^{2}+b(y-{y}_{0}{)}^{2}=c$,

or of the form$a{x}^{2}+b{y}^{2}+cx+dy+e=0$,

where $({x}_{0},{y}_{0})$ is the center of the ellipse and the ratio between the two axes of the ellipse is described by the ratio between $a$ and $b$ (how?).This online exercise can either plot an ellipse and ask you to recognize its equation among a list to choose from, or give an equation and ask you to recognize the plotted ellipse among a list to choose from.
