Proportional and Nonproportional Relationships Using a Table

Which statement best describes the relationship of x and y in the table? Hint: Find the ratio between y and x. If it is constant, that value is the Constant of Proportionality (AKA: Unit Rate) and the relationship is proportional. You can determine if it is constant by dividing y by x for every (x,y) pair. Money/Hours. (k=y/x) If the quotient is the same for every ratio of y/x, then the relationship is proportional and the quotient is the Constant of Proportionality.
