Final answer:
The yy-intercept of 75 in the equation y = 55x + 75 represents the flat fee or the total labor charges to fix a car when no hours have been worked.
Step-by-step explanation:
The yy-intercept of the function represented by the equation y = 55x + 75 is 75, which in the context of the problem represents the total labor charges to fix a car when no hours of work have been logged (that is, when x = 0). This charge is likely a flat fee that is charged regardless of the hours worked.
The intercept is important as it forms the starting point of the cost before any hourly work is added. In this context, it does not represent items such as the total time of the trip, the number of gallons of gas used per hour, total cost to drive from one location to another, average speed, or the distance between two places.
