.

1.   You correctly found one of many possible solutions.

2.   There are MANY possible solutions.   They are

                 + = 1

        with 5 =   and with not necessary integers "a" and "b".

3.   For ellipses, there are three major types/forms of equations:

      a)   a canonical equation.
            See the lesson   Ellipse definition, canonical equation, characteristic points and elements   in this site;

      b)   the standard form equation.
            See the lesson   Standard equation of an ellipse   in this site;

      c)   the general form equation.
            See the lesson   General equation of an ellipse   in this site.
