If y is the dependent variable and x is the independent variable, then the slope is Slope=ΔyΔxwhere Δy is the change in y (difference in y) and Δx is the change in x (difference in x).
If you wanted to power the city of Seattle using wind power, how many windmills would you need to install? Questions like these can be answered using rates and proportions.
