Independent variable: Number of cans Dependent variable: Soda(oz) The relationship represents the total amount of soda measured in ounces in x-number of cans Equation: y=12x

Work Step by Step

The number of cans is independent variable because it lies on the x-axis The Soda amount is dependent variable because it lies on the y-axis Equation: Slope: $\frac{(y_{2}-y_{1})}{(x_{2}-x_{1})}$ $\frac{(24-12)}{(2-1)}$ $\frac{12}{1}$ slope=12 since there is no y-intercept, Equation: y=12x
