In the context of the function \( y = 80x + 2 \), where \( y \) represents the speed in miles per hour and \( x \) typically represents time in hours, the quantity that describes the x-axis is time in hours. This is because the variable \( x \) in this function indicates the time elapsed during the trip, which aligns with how the graph is modeled. The \( y \)-axis (speed in miles per hour) shows how the speed changes over that time.
A graph of the function y = 80x + 2 models carlis road trip with her speed measured in miles per hour the graph includes the two hours of stops shell make using this information define which quantity describes the x-axis
