In the function \( y = 80x + 2 \), \( x \) represents a quantity that is used to calculate the value of \( y \). Given that this function models Carli’s road trip along with her speed in miles per hour and includes stops, the variable \( x \) most appropriately represents **time in hours**.
Thus, the quantity that describes the x-axis is **time in hours**.
Thus, the quantity that describes the x-axis is **time in hours**.
