Answer:
[tex]y=20x[/tex]
20 gallons/mile
Step-by-step explanation:
Although there are not statements below, we can find through this two graphs, two basic pieces of information
1) This function since it is a linear function with b=0, then this graph (crosses the origin) and it is a proportional one we can find
(2,40) (4,80)
[tex]k=\frac{y}{x}\Rightarrow k=\frac{40}{2}=\frac{80}{4}=20[/tex]
[tex]y=20x[/tex]
2) Given the slope we can find the the consumption rate. 20 gallons per mile.
