Find the standard form of the equation of the ellipse satisfying the given conditions. Foci: \( (-2,0),(2,0) ; y \)-intercepts: -9 and 9 Type the standard form of the equation. (Type an equation. Simplify your answer.)

Find the standard form of the equation of the ellipse satisfying the given conditions. Foci: \( (-3,0),(3,0) \); vertices: \( (-10,0),(10,0) \) Type the standard form of the equation. (Type an equation. Simplify your answer.)

Analyze the equation. That is, find the center, vertices, and foci of the ellipse and graph it. \[ \frac{x^{2}}{49}+\frac{y^{2}}{4}=1 \]
