Question

An ellipse has a center at the origin, a vertex along the major axis at (10, 0), and a focus at (8, 0).

Which equation represents this ellipse?

Answer 1

In standard form x^2/64 + y^2/100 = 1

Explanation:

The major axis is the y axis because 10 has a larger value than 8.

8x8 = 64

10 x10 = 100
