Ethan started the day with an irrigation pipe of 120 feet long. He used the equation L=15s+20 to determine the total length of the pipe as new sections of pipe, s, were welded on to the end. What is the slope of the line? What does the slope represent in the context of the problem?
m=15, so 15 feet is added to the length for each section of pipe
