Hi. Is there any way to know if a ellipse in the form has a horizontal or vertical major axis without changing into standard form. For example, if I have the ellipse can I tell if it is horizontal or vertical without changing it into standard form. I would think that the quadratic term ( ) with the lower coefficent would be over , allowing one to determine whether it was horizontal or vertical, but I could be wrong. Could someone tell me if I am correct? Thanks!
