Final answer:
A slope of 1/4 means that for every 4 units sold, there is an increase of 1 million in revenue. The student has asked what the slope of 1/4 means in context.
Step-by-step explanation:
The student has asked what the slope of 1/4 means in context. This slope means that for every increase of 1 unit sold, there is an increase of $0.25 million in revenue. Therefore, the correct answer is option A: there is an increase of 1 million in revenue for every 4 units sold. This interpretation of the slope is derived from understanding that in a linear equation, the slope (rise over run) indicates how the dependent variable (in this case, revenue) changes for each one unit increase in the independent variable (units sold).
The slope of 1/4 means that for every one unit increase in the independent variable, the dependent variable increases by 1/4 units. In the context of revenue, it means that for every one unit sold, the revenue increases by 1/4 units.
