#### Answer:

Vertices are

#### Explanation:

The given equation,

is clearly the standard form of equation of an ellipse with center at

Eccentricity is

And hence focii are

As it is an ellipse question of asymptote does not arise

The graph appears as below.

graph{x^2/9+y^2/25=1 [-10, 10, -5, 5]}
