Hi,
ellipse with x-intercepts (±2,0) and y-intercepts (0,±5)  
 {{{x^2/2^2 + y^2/5^2 = 1}}}
    Standard Form of an Equation of an Ellipse is {{{(x-h)^2/b^2 + (y-k)^2/a^2 = 1 }}} 
where Pt(h,k) is the center. (a variable positioned to correspond with major axis)
 a and b  are the respective vertices distances from center
