You can put this solution on YOUR website!
Vertices (0,0) and (0,8) mean the center is (h,k) = (0,4) and the major axis is vertical, with semi-major axis (a) length 4. The equation is
You have the coordinates of the center and the value of parameter a. So you can determine a^2, and all you need to finish writing the equation is the value of b^2.
To find b^2, use  , where c is the distance from the center to each focus.
Since you know the center and are given the focus, you can determine c, and thus calculate b^2.
Then you will have all you need to write the equation.
