During a snowstorm, Mayerlin tracked the amount of snow on the ground. When the storm began, there was 1 inch of snow on the ground. For the first 6 hours of the storm, snow fell at a constant rate of 1 inch every 3 hours. The storm then stopped for 6 hours and then started again at a constant rate of 2 inches per hour for the next 2 hours. Make a graph showing the inches of snow on the ground over time using the data that Mayerlin collected.
