An ellipse has the centre at \( S=[-1;3] \), the semi major axis with the length of \( 3 \) and the semi minor axis with the length of \( 2 \). The semi major axis is parallel to \( y \) axis. The equation of the ellipse is:
\( \frac{(x+1)^2}4+ \frac{(y-3)^2}9 = 1 \)
\( \frac{(x+1)^2}9 + \frac{(y-3)^2}4 = 1 \)
\( \frac{(x-1)^2}4+ \frac{(y+3)^2}9 = 1 \)
\( \frac{(x+1)^2}4-\frac{(y-3)^2}9 = 1 \)
\( \frac{(x+1)^2}4 + \frac{(y-3)^2}9 = -1 \)
