In Exercise, some applications involving straight lines are shown.
A survey of the traffic on a particular highway showed that the number of cars passing a particular point each minute varied linearly from 6:30 a.m. to 8:30 a.m. on workday mornings. The study showed that an average of 45 cars passed the point in one minute at 7 a.m. and that 115 cars passed in one minute at 8 a.m. If n is the number of cars passing the point in one minute and t is the number of minutes after 6:30 a.m., find the equation relating n and t, and graph the equation. From the graph, determine n at 6:30 a.m. and at 8:30 a.m. What is the meaning of the slope of the line?
