An ellipse has a vertex at (-5,0), a co-vertex at (0,4), and a center at the origin. Which is the equation of the ellipse in standard form?

Question

anonymous · Answer

The standard equation of an ellipse is supposed to look like this:

x^2/a^2 + y^2/b^2 = 1

anonymous · Answer

Vertices ( +/- a , 0 ) and Co-vert ( 0, +/- b)

anonymous · Answer

Just plug it in and simplify and you have your answer.

anonymous · Answer

so in this case, a is +/- 5 and b is +/-4?

anonymous · Answer

Which would make the answer C

anonymous · Answer

No. The vertex(multiple vertexs is vertices) at (-5,0), and co-vertex at (0,4)
