**Reiny**, Monday, October 5, 2009 at 9:16pmfirst find the centre, which would be the midpoint of the vertices,

it would be (2,3)

the length of the minor axis is 4, so b = 2

sofar we would would have

(x-2)^2/a^2 + (y-3)^2/4 = 1

but (5,3) lies on it, so

(5-2)^2/a^2 + (3-3)^2/4 = 1

9/a^2 = 1

a^2 = 9

final equation

(x-2)^2/9 + (y-3)^2/4 = 1
