    here is all you need to answer this question: \[\large \frac {(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2}=1 \] where (h,k) is the center vertices for this ellipse: (h,k\(\pm \)b) length of the minor axis: 2a length of major axis: 2b foci: (h,k\(\pm \)c where \(\large c^2 =b^2-a^2\)

    \(\large \frac {(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2}=1\) \(\large \frac {(x+5)^2}{5^2}+\frac{(y-7)^2}{12^2}=1\)
