The following situation can be described by a linear function. Draw a graph of the function and use the graph to answer the given quesion. Be sure to identify the independent and dependent variables. Then briefly discuss whether a linear model is reasonable for the situation described. The maximum speed of a semitrailer truck up a hill varies with the weight of its cargo. With no cargo, it can maintain a maximum speed of 40 miles per hour. With 20 tons of cargo, its maximum speed drops to 35 miles per hour. At what load does a linear model predict a maximum speed of 0 miles per hour? Question content area bottom left Part 1 The weight of the cargo is the dependent independent variable. The speed in miles per hour is the independent dependent variable. Part 2 Use the graphing tool to graph the line. Part 3 The speed of the truck is 0 when there is enter your response here ton(s) of cargo. Part 4 Is a linear model reasonable for the situation? A. The model is reasonable because the maximum speed of any vehicle will decrease with more load. B. The model is most likely
