Answer:
![\dfrac{x^2}{49}+\dfrac{y^2}{25}=1.](https://tex.z-dn.net/?f=%5Cdfrac%7Bx%5E2%7D%7B49%7D%2B%5Cdfrac%7By%5E2%7D%7B25%7D%3D1.)
Step-by-step explanation:
The equation of the ellipse is
![\dfrac{x^2}{a^2}+\dfrac{y^2}{b^2}=1.](https://tex.z-dn.net/?f=%5Cdfrac%7Bx%5E2%7D%7Ba%5E2%7D%2B%5Cdfrac%7By%5E2%7D%7Bb%5E2%7D%3D1.)
If the vertex of the ellipse is at point (-7,0), then a=7.
If the co-vertex of the elllipse is at point (0,-5), then b=5.
The equation of the ellipse is
![\dfrac{x^2}{7^2}+\dfrac{y^2}{5^2}=1,](https://tex.z-dn.net/?f=%5Cdfrac%7Bx%5E2%7D%7B7%5E2%7D%2B%5Cdfrac%7By%5E2%7D%7B5%5E2%7D%3D1%2C)
![\dfrac{x^2}{49}+\dfrac{y^2}{25}=1.](https://tex.z-dn.net/?f=%5Cdfrac%7Bx%5E2%7D%7B49%7D%2B%5Cdfrac%7By%5E2%7D%7B25%7D%3D1.)
