The coordinates of the center and one of the vertices tell us that the major axis is horizontal.

The standard form of the equation of an ellipse with horizontal major axis is

In the equation, (h,k) is the center of the ellipse; a is the semi-major axis (distance from the center to each vertex) and b is the semi-minor axis.

The given information makes it easy to find the values of a and b and thus write the equation.

I leave that easy part to you.
