Considering the given table and the periodicity concept, it is found that the data set is not periodic.
<h3>What is the period of a data-set?</h3>
The period of a function is given by the <u>distance between it's repetitions</u>.
An example of a periodic data-set with a period of 3 would be 1,2,3,1,2,3,1,2,3,...
In this problem, looking at the table, it is found that there are no patterns of repetitions, that is, the number of cars washed do not follow a repeated pattern, hence the data set is not periodic.

What is a Line Function ?
A line function is what can be written in the form of
y =mx +c
where m is the slope and c is the intercept on y axis.
The equation given here is y = (3/5)x -5
m = 3/5
c = -5
