In a linear model:
[tex]f(x)=mx+b[/tex]The coefficient of x, which is m, is the rate of change of the function f with respect to changes in the value of x. In the context of the problem, the coefficient of x tells us the amount of money that Jim earns per hour.
The constant term b is the initial value of the function f when x=0.
Since the given linear model has no constant term, it means that the initial value is 0. In other words, Jim will earn $0 if he works 0 hours.
Therefore, the correct choice is Option A) There is no initial amount of money he gets paid prior to starting.
