Answer: Non-proportional
Step-by-step explanation:
The unit rate for the gas per gallon is $3.17. You want to find out if that is equal to the amount you would pay for 10 gallons at once. If you multiply the unit rate by ten, you would get 10 gallons = $31.70
So...you know that it is not proportional
Answer:
The unit rate of $10 per hour.
Step-by-step explanation:
Given



See attachment for graph
Required
What does the given point represents
From the attachment, the origin of the graph is:

and we have the given point to be:
Calculate the slope (m)




The slope represents $10/1 hour
Hence:
means the unit rate is $10 per hour
