Hi(0,0),(0,8);
major axis: 2a = 12, a = 6
and C(0,4) and 8/2 = 4, foci distance from center
b^2 = 20



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
