Which is the proportional relationship for this graph?

For every the canoe is rented, the total cost goes up by $12.

Step-by-step explanation:

To find the proportional relationship, Take two points from the graph, for example (2, 24) and (4, 48), and put them into the slope formula:

Solve:

48 - 24 = 24

4 - 2 = 2

24/2 = 12

The proportional relationship between the hours the canoe is rented and the total cost is $12.

Hope this helps :)
