Analyze each equation. That is, find the center, vertices, and foci of each ellipse and graph it. \[ \frac{x^{2}}{9}+\frac{y^{2}}{25}=1 \] What are the coordinates of the center? (0,0) (Type an ordered pair.) What are the coordinates of the vertices? \( \square \) Type an ordered pair. Use a comma to separate answers as needed.)
