While it's not strictly necessary, why not draw a picture of this ellipse?  
" a " is the length of the major axis, whereas " b " is the length of the minor axis.
The standard equation of a horizontal ellipse centered at (0,0) is$$\frac{ x^2 }{ a^2 }+\frac{ y^2 }{ b^2 }=1$$

mathmale · Answer

With this info., can you now determine the values of " a " and " b "?
If so, substitute them into the equation above, and you'll have the desired equation of this ellipse.
