The interpretation of the slope in this situation:
There is a set fee to use a transportation service and a rate for each mile traveled. To travel 2 miles, the total cost is $11. To travel 5 miles, the total cost is is $15.50.
Your team can earn a bonus $100 if you can give the fee to use the service.
The cost to travel is $1.50 per mile.
Bonus: The fee to use the service is $8.
The interpretation of the equation y = 1.5x, where y is the total cost in dollars, and x pounds of apples.
Each pound of apples costs $1.50
