The change in output from adding one more worker is the A) marginal product of labour.

Explanation:

The marginal product of labor (MPL) means measuring the actual output following the hiring of labor while other factors that may affect productivity remain the same or constant. The marginal product of labor help firms to determine whether the new employee is an asset or a liability to the company.

If the MPL is lower than the cost of the employee, it means the employee is a liability. The production demand will determine how much labor requires. It also requires being cautious of the MPL and the employees' salaries. A good business deal requires MPL to be higher than the salaries.

A line of best fit can only be drawn if there is strong positive or negative correlation. The line of best fit does not have to go through the origin. The line of best fit shows the trend, but it is only approximate and any readings taken from it will be estimations.
