How would I know whether the graph of a given ellipse equation is vertical or horizontal?

When the equation is in the form
(x/a)² + (y/b)² = 1
The constants "a" and "b" are the semiaxis lengths in the corresponding (x and y) directions. If a > b, the long axis is horizontal. If b > a, the reverse is true.
See the attached for examples.
