The total cost represented by the graph has a higher initial/starting fee that must be paid no matter how many days it is rented
A linear equation is given by:
y = mx + b
where y, x are variables, m is the rate of change, b is the initial vale of y (y intercept).
Let y represent the total cost of renting a forklift for x days.
Given the equation:
y = 30x + 30;
Therefore the starting or initial fee that must be paid is $30
From the graph, the y intercept is at (0, 40), hence the starting or initial fee that must be paid is $40
The total cost represented by the graph has a higher initial/starting fee that must be paid no matter how many days it is rented
