Answer:
It is not linear.
Step-by-step explanation:
If it were, than for every change in hours worked, the slope of the line would be the same (or the cost would change be the same amount).
From 2 to 3 and 3 to 4 hours, the change in cost is $20. However, from 1 to 2 hours the change is $15.
Since it is not uniform, it is not linear.
