The quantity that describes the x-axis in the context of the function \( y = 80x + 2 \), modeling Carli’s road trip with speed in miles per hour and including two hours of stops, is time in hours.
In this case, \( x \) represents the time spent traveling, which is typically measured in hours, while \( y \) represents the total miles traveled.
