Answer:
option D
Step-by-step explanation:
![x^{2} + y^{2} = 16\\\\x^{2} = 16- y^{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%2B%20y%5E%7B2%7D%20%3D%2016%5C%5C%5C%5Cx%5E%7B2%7D%20%3D%2016-%20y%5E%7B2%7D)
equation 2:
![\frac{x^{2}}{4} - \frac{y^{2}}{25} = 1](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B2%7D%7D%7B4%7D%20-%20%5Cfrac%7By%5E%7B2%7D%7D%7B25%7D%20%3D%201)
so we have:
![\frac{16- y^{2} }{4}-\frac{y^{2}}{25}= 1](https://tex.z-dn.net/?f=%5Cfrac%7B16-%20y%5E%7B2%7D%20%7D%7B4%7D-%5Cfrac%7By%5E%7B2%7D%7D%7B25%7D%3D%201)
