Number of cans is the independent variable and ounces of soda is dependent variable. The relationship is that for every additional can, the quantity of soda increases by 12oz. The equation of the relationship is y=12x. The graph is attached below.
Work Step by Step
The equation is y=12x because the slope is 12 as for increase in the independent variable, the dependent variable is increased by 12. There is no y-int as when 0 cans, there are 0 oz.
