Example 2
At a roadside farm stand, you can buy 5 pounds of any of the vegetables for a total cost of $6.
Determine the slope of the line formed by the proportional relationship between the number of
pounds purchased and the cost of the vegetables. Explain what the slope means in the context of the
problem. Finally, use the slope to determine how many pounds of vegetables can be purchased for
$13. Assume there is no sales tax.
