Step-by-step explanation
The standart form
![((x-h)^2)/(a^2)+((y-k)^2)/(b^2)=1](https://img.qammunity.org/2023/formulas/mathematics/college/l0626bn68eeug6hf6kdo2ks0r7t63wrkx6.png)
h and k represents the center of the ellipse, in this case.
The center of the ellipse is the point (0, 0)
a represents the distance between the center and the vertex, in this case
The value for a is: 9
b represents the distance between the center and the co-vertex, in this case
The value for b is: 3
Answer
The center of the ellipse is the point (0, 0)
The value for a is: 9
The value for b is: 3
