In the function \( y = 80x + 2 \) that models Carly's road trip, the variable \( x \) represents the time in hours that she is driving, excluding the 2 hours of stops. Therefore, the x-axis represents the time spent driving in hours. The overall time of the trip would then include both the driving time and the time spent on stops.
A graph of the function y= 80x +2 models carlis road trip with her speed measured in miles per hour. The graph includes the 2 hours of stops she’ll make. Using this information define which quantity describes the x-axis
