Question

anonymous · Answer

I totally forgot how to do this, and Google isn't helping. The x-axis, or horizontal, is the major one, and its 8in. The y-axis is 6in.

loser66 · Answer

main axis is 8 inches--> a = 4
minor axis is 6 inches --> b =3
just plug them into the formula
$$\dfrac{x^2}{16}+\dfrac{y^2}{9}=1$$
That's it

I finally figured that out, I was trying to fill in the x and y. Silly me. Thank you so much! :DDD
