Hi

major axis: a = 4

(3,0)and (-3,0);    and 6/2 = 3, foci distance from center 

   b^2 = 7

 



Standard Form of an Equation of an Ellipse is  

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

 and ±are the foci distances from center: a > b
