Your equation is
You are given the length of the minor axes to be 2 therefore you have the points (0,2),(8,2),(4,0),(4,4) and centre (4,2), major axis is 4.
You have lots of information here, firstly can you find (h,k)?
Find standard form of the equation of ellipse with given characteristics.
Vertices: (0,2), (8,2)
minor axis of length 2
With that information I found the center: (4,2)
minor axis of length 2 means I would use 2b=2?
So b=1
I am lost after this that.
