Standard formula for ellipse centred at origin:
$\large \frac{x^2}{a^2}+\frac{y^2}{b^2}=1$
c=distance from centre to focus = $sqrt(|b^2-a^2|)$
Axis (line joining foci) is horizontal when a>b
Axis is vertical when b>a
Compare standard equation to find a and b (distances from centre to vertices)
