2.
![(x^2)/(16)+(y^2)/(9)=1.](https://img.qammunity.org/2020/formulas/mathematics/middle-school/fr56he916eg5473woi3gkcbuc9hioyv5bc.png)
Explanation:
The equation of the ellipse is
![(x^2)/(a^2)+(y^2)/(b^2)=1.](https://img.qammunity.org/2020/formulas/mathematics/middle-school/d1pklliy6qqb11vp8oww2r20rorhyei513.png)
1. If the vertex of the ellipse is at point (6,0), then a=6.
If the co-vertex of the elllipse is at point (0,-5), then b=5.
The equation of the ellipse is
![(x^2)/(6^2)+(y^2)/(5^2)=1,](https://img.qammunity.org/2020/formulas/mathematics/middle-school/du45o91egnksm8g8kle7z3ncsa4q6a6nne.png)

2. If the vertex of the ellipse is at point (4,0), then a=4.
If the co-vertex of the elllipse is at point (0,3), then b=3.
The equation of the ellipse is
![(x^2)/(4^2)+(y^2)/(3^2)=1,](https://img.qammunity.org/2020/formulas/mathematics/middle-school/9gv28n379req37bbn3tlejt3jf7f39hjj3.png)
