Which is the proportional relationship for this graph?

Answer:
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: [tex]\frac{y2-y1}{x2-x1}[/tex]
[tex]\frac{48-24}{4-2}[/tex]
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 :)
