Final answer:
To graph the inches of snow on the ground over time, create a line graph and plot the data points based on Gabriella's observations.
Step-by-step explanation:
To graph the inches of snow on the ground over time, we can create a line graph. The x-axis represents time in hours, and the y-axis represents the inches of snow. We can plot the data points based on Gabriella's observations.
First, we start with 5 inches of snow on the ground when the storm began. For the first 2 hours, the snow fell at a constant rate of 2 inches per hour, so we can plot (2, 9) as a data point.
Then, the storm stopped for 5 hours, so we have a gap in the graph. After the break, the snow fell at a constant rate of 1 inch per hour for the next 3 hours. This means we can plot (10, 10) as a data point.
Finally, we connect the data points with a line to represent the inches of snow on the ground over time.
