**
standard form of equation for an ellipse with horizontal major axis:
(x-h)^2/a^2+(y-k)^2/b^2=1, (a>b), (h,k)=(x,y) coordinates of center
For given problem:
center: (0,0)
length of horizontal major axis=8=2a
a=4
a^2=16
..
length of vertical or minor axis=6=2b
b=3
b^2=9
..
equation:
x^2/16+y^2/9=1
