During a snowstorm, Connor tracked the amount of snow on the ground. When the storm began, there were 5 inches of snow on the ground. Snow fell at a constant rate of 3 inches per hour until another 9 inches had fallen. The storm then stopped for 7 hours and then started again at a constant rate of 1 inch per hour for the next 6 hours. Make a graph showing the inches of snow on the ground over time using the data that Connor collected.
