Answer:
The ratio is same for every pair of values.
Step-by-step explanation:
See the given graph.
The graph is a straight line which proves that the Rent in dollars is increasing at a constant rate with respect to time in Days. So, for a fixed change in time in Days, there will be a fixed change in the rent in Dollars.
Therefore, yes the function is proportional and the ratio is same for every pair of values.
Hence, option 1 is correct.
