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.
y = k / x 1 / 2 = k / 10 2 k = 10 k = 5 Also:  1/3 = 5/15,  1/4 = 5/20,  1/5 = 5/25. Answer: This is an inverse variation. An equation is : y = 5 / x .
