#### Answer

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
