The vertices are

The foci are

The asymptotes are

#### Explanation:

The equation is a left right hyperbola.

The center is

The vertices are

The slopes of the asymptotes are

The equations of the asymptotes are

To calculate the foci, we need c,

and the foci are

graph{x^2/9-y^2/9=1 [-12.66, 12.65, -6.33, 6.33]}
