The x-axis is the major axis since 3+%3E+sqrt%283%29
The general form is:
%28x%5E2%29%2F%28a%5E2%29+%2B+%28y%5E2%29%2F%28b%5E2%29+=+1
Where the x-intercepts are at +/- a
and the y-intercepts are at +/- b
given:
x-intercepts +/- 3
y-intercepts +/- sqrt%283%29
a+=+3 and -a+=+-3
b+=+sqrt%283%29 and -b+=+-sqrt%283%29
a%5E2+=+9
b%5E2+=+3
The equation is:
%28x%5E2%29%2F9+%2B+%28y%5E2%29%2F3+=+1
