Write the equation of the ellipse that meet each set of conditions.
1. The endpoints of the major axis are at (-11,5) (7,5). The endpoint of the minor axis are (-2,9) and (-2,1)
2. The ellipse has center origin a=1 and e=3/4
How would I write these equation I mean for number one I got (2,5) as the center using midpoint formula. But how would I get the denominator in the formula (x-h^2)/a^2 + (y-k^2)/b^2 =1
