The equation y=7x gives the relationship between the number of road projects, x, and the number of weeks it takes a crew of workers to complete all the projects, y. What is the constant of proportionality? What does it mean in the context? 1.The constant of proportionality is 7. It takes the crew of workers 7 days to complete 1 road project. 2. The constant of proportionality is 7. It takes the crew of workers 7 weeks to complete 1 road project. 3. The constant of proportionality is 7. It takes the crew of workers 7 days to complete all of their road projects. 4. The constant of proportionality is 7. It takes the crew of workers 7 weeks to complete all of their road projects.

The correct answer is:

2. The constant of proportionality is 7. It takes the crew of workers 7 weeks to complete 1 road project.

In this context, the constant of proportionality means that for every additional road project, it takes the crew of workers 7 weeks to complete it. This implies that the time required to complete all the road projects is directly proportional to the number of road projects.
