Question

graph of the function y = 80 + 2 models Carl's road trip, with her speed measured in
miles per hour. The graph includes the two hours of stops she'll make. Using this information, define which quantity describes the x-axis. (1 point)
O miles traveled
O direction traveled
• time in hours
• speed traveled

Answer 1

In the context of the function \( y = 80 + 2 \), where \( y \) likely represents Carl's total distance traveled (in miles) and \( x \) represents time, the x-axis would describe the time elapsed during the trip, including her stops.

Therefore, the correct option to describe the x-axis is:

• **time in hours**
