To determine the rate of change in units per month, we need to find the slope of the line connecting the production values over time. Here’s how you can calculate it:

Identify the Points:

January: (1,150) (where x=1 for January and y=150 units)

March: (3,300)(where x=3 for March and y=300 units)

Use the Slope Formula: The slope m (rate of change) is calculated as:

Substituting the values:
