During a snowstorm, Noah tracked the amount of snow on the ground. When the storm began, there was 1 inch of snow on the ground. For the first 4 hours of the storm, snow fell at a constant rate of 3 inches per hour. The storm then stopped for 2 hours and then started again at a constant rate of 2 inches per hour for the next 6 hours. Make a graph showing the inches of snow on the ground over time using the data that Noah collected.
