vocaloid · Answer

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

sloppycanada · Answer

I'm referring to ellipses.

Do you want me to give you a sample problem?

sure, if you'd like

vocaloid · Answer

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

vocaloid · Answer

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

sloppycanada · Answer

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

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

sloppycanada · Answer

So it's y = -2?

agent0smith · Answer

No, i don't know how you got that

sloppycanada · Answer

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