Question

How do I determine if an equation has a major axis as the y-axis?

Answer 1

what kind of equation? are you talking about ellipses or hyperbola, by chance?

Answer 2

I'm referring to ellipses.

Answer 3

Do you want me to give you a sample problem?

Answer 4

sure, if you'd like

Answer 5

or, put simply:

if the larger denominator is under x^2, then the major axis is the x-axis
if the larger denominator is under y^2, then the major axis is the y-axis

Answer 6

(just make sure the equation is in the right form ^)

Answer 7

\[\frac{ (x-2)^2 }{ 49 } +\frac{ (y+1)^2 }{ 25 } = 1\]

Answer 8

As @voocaloid said, look at which has the bigger denominator.

Answer 9

So it's y = -2?

Answer 11

No, i don't know how you got that

Answer 12

Well, there's no x = ? or whatever in any of my choices, so i figured it might've been a mistake.
