Write an equation for an ellipse if the endpoints of the major axis are at (1,6) and (1,-6) and the endpoints of the minor axis are at (5,0) and (-3,0).

My answer is y^2/36 + (x-1)^2/16 = 1.

Is this correct?

Thanks.

It looks like the answer I posted yesterday. Are you asking for second opinions?

well, the center is at (1,0) and the major axis is up and down

Half the height is 6 and half the width is 4

(y-0)^2/6^2 + (x-1)^2/4^2 = 1

so I agree.

hmmm, we often agree :)
