The equation y = 3/4

Question

x describes the number of calls y a salesperson makes in x minutes. How does y change as x​ changes? Describe what the change means in this situation.

Answer 1

The equation y = 3/4x describes a linear relationship between the number of calls made, y, and the time spent making the calls, x.

As x changes, y will also change. Specifically, as x increases, y will also increase, and vice versa. This means that the more time the salesperson spends making calls, the more calls they will be able to make.

In this situation, the change in y as x changes represents the salesperson's productivity or efficiency in making calls. The equation tells us that for every 4 minutes, the salesperson is able to make 3 calls. So, for example, if they spend 8 minutes making calls, they would be able to make 6 calls.
