Use a scale of 2 cm to represent 1,000 units on the x-axis & 2 cm to represent $50,000 on the y- axis. e) Using the line of best-fit, determine the company's fixed cost per month and the variable cost per unit. (Use 0 & 5,000 units.) f) Which of the two methods appear more appropriate? Explain your answer.
