with options

pls help

note to self this is question 13

Answer 1

The ratio
`\frac{\textrm{Rent}}{\textrm{Number of Days}}` is same for every pair of values.

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
`\frac{\textrm{Rent}}{\textrm{Number of Days}}` is same for every pair of values.

Hence, option 1 is correct.
