An airplane is flying high over Siberia and the fuel tank starts leaking. The tank contained 80 gallons of fuel when it started leaking and is leaking at a rate of 10 gallons each minute. Think and answer the following questions regarding this scenario. 1. How does the amount of fuel in the tank change as time passes? 2. If you need to graph the relationship between the amount of fuel in the tank and the time spent flying since the fuel leak started, does it matter which quantity is represented on the horizontal axis? 3. How did you decide on the scale unit? How might the picture of the situation change if the scale unit were different? 4. Where on the graph does it indicate that the fuel tank is empty? 5. Why does it make sense to connect the points in the graph to make it be a straight line
