Standard form of an ellipse with a vertical major axis is defined as:
[tex] \frac{ x^{2} }{ b^{2} } + \frac{ y^{2} }{ a^{2} } =1 [/tex] where a is greater than b.
recall if the vertical major axis is 6, then the value of a = 3 and if the minor axis has a length of 4, then the value of b = 2. We can now write our equation of the ellipse:
[tex] \frac{ x^{2} }{ 2^{2} } + \frac{y^{2} }{ 3^{2} } =1[/tex]
So you can see your answer will be the last choice!
