    the ellipse equation

    \frac{(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2}=1

    since...(h,k),,the...center...they...gave..you..th  e..center

    you can find a with this statement "one vertex at (1,1)" and you know that the center is "(3,1)" when you find a and substitute a and the center in the equation then you have just one variable "b" you can find it try..

    best wishes
