Question

The cost to rent a scooter is $10 plus $8 each for each hour of use. If the cost were to be modeled with a linear equation and graphed, what would be the slope?

Answer 1

$8/hour

Explanation:

If cost is the dependent variable and time is the independent variable the slope of the cost equation will be the hourly rate for the rental: $8/hour. That is, the cost increases by $8 for each hour increase in rental time.
