In the given function \( y = 80x + 2 \), where \( y \) represents Carli’s speed in miles per hour and \( x \) is a variable representing another quantity, the appropriate choice for the x-axis would be **time in hours**.
This is because the function represents Carli's speed at different points in time, and typically in such functions, time is used as the independent variable (x-axis).
