Answer: Option C. Ellipse
Step-by-step explanation:
The general equation of an ellipse has the following form:
![\frac{(x-h)^2}{a^2} + \frac{(y-k)^2}{b^2} =1](https://tex.z-dn.net/?f=%5Cfrac%7B%28x-h%29%5E2%7D%7Ba%5E2%7D%20%2B%20%5Cfrac%7B%28y-k%29%5E2%7D%7Bb%5E2%7D%20%3D1)
Where the point (h, k) is the center of the ellipse
In this case we have the equation
![\frac{(x-9)^2}{4} + \frac{(y+2)^2}{25} =1](https://tex.z-dn.net/?f=%5Cfrac%7B%28x-9%29%5E2%7D%7B4%7D%20%2B%20%5Cfrac%7B%28y%2B2%29%5E2%7D%7B25%7D%20%3D1)
Note that its shape matches that of a ellipse with center (9, -2)
![a=\sqrt{4} \\a=2\\\\\\b=\sqrt{25}\\b=5](https://tex.z-dn.net/?f=a%3D%5Csqrt%7B4%7D%20%5C%5Ca%3D2%5C%5C%5C%5C%5C%5Cb%3D%5Csqrt%7B25%7D%5C%5Cb%3D5)
Therefore the answer is the obtion C
