Find the slope of the data, using the formula of the slope:
Use 2 pairs of data to find it:
In this case the slope is 24.50.
It represents the cost per ticket.
Now, we can use this slope and a pair of data to find the equation that represents this situation, using the point slope formula:
According to this the y intercept of the equation is 9.50, which is also the service charge.
Knowing this information allows us to determine that the statements that are true are I and II.
