Answer:
The equation of the ellipse is
This is the explicit form of an ellipse, where and , which means the center of the ellipse is at .
Remember that the greatest denominator in an ellipse is the parameter and the least is , so
The length of the major axis is:
The length of the minor axis is:
Vertices are and , because the center is not the origin of the coordinate system so, the vertices are displaced. The least axis vertices are: and .
The foci are on the major axis, so their vertical coordinate is 1, their horizontal coordinate depends on parameter , which is related as the following
Therefore, the foci coordinates are and .
The ladus rectus is
The eccentricity is
Additionally, the graph is attached, there you can observe some elements of the ellipse.
(Remember, all elements of an ellipse depend on the three parameters a, b and c, that's what you need to find first)
