Answer:
The answer to your question is letter A
Step-by-step explanation:
From the graph, we conclude that it is a vertical ellipse with center (0, 0).
Also from the graph, we calculate a and b
a = 11, a is the distance from the center to the vertical vertex
b= 9, b is the distance from the center to the horizontal vertex
Equation
[tex]\frac{x^{2}}{9^{2}} + \frac{y^{2}}{11^{2}} = 1[/tex]
Simplification
[tex]\frac{x^{2}}{81} + \frac{y^{2}}{111} = 1[/tex]
