If you have the equation y=1/2x4
How would you set up a table for the equation for x, y (xy)?

Do you mean
a) y = [1/(2x)] 4
or
b) y = (1/2)x  4
or
c) y = 1 / (2x4)
???????????????????????? 
It is a table with x in the first box at the top y is in the second box and (xy) is the third box. Now under each varable you are supposed to complete the table using the equation. There are 5 rows down under each varable.
x y (xy)
______1______________
2____________________
______4______________
2____________________
8____________________
Then solve for x, y and (x,y) 
But I do not know what your equation is. Do you mean a, b, or c ?
if it is b then
y = (1/2)x  4 is the same as x = 2(y+4)
now if y = 1 is given
then x = 6
and xy = 6
if x = 2 is given
then y = 3
and xy = 6
if y = 4 is given
then x = 0
and xy = 0
etc
