Question

Determine whether the relation shown in the table is a direct variation, an inverse variation, or neither. If it is a direct or inverse variation, write an equation for the function.

x : 10      15       20       25
y:  1/2    1/3     1/4      1/5

Ok The relation is one that is inverse...in other words y = k/x
to find k just put 10 is for x and 1/2 in for y and you'll see that k = 5.
y = 5/x is your equation.
