To help you complete the equation for Luis renting a paddleboat based on the line graph, I would need to know the specific details represented in the graph, such as the deposit amount, the hourly fee, and how these values relate to the axes.
A common equation for this type of situation might look like:
\[ \text{Total Cost} = \text{Deposit} + (\text{Hourly Fee} \times \text{Hours Rented}) \]
If you share the relevant points from the graph (e.g., the deposit value at 0 hours, the hourly fee for various hours), I can assist you in formulating the accurate equation. Please provide those details!
