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 this context

Answer 1

The constant of proportionality is 7.

In this context, the constant of proportionality means that for every unit increase in the number of road projects, the number of weeks it takes for the crew of workers to complete all the projects will increase by a factor of 7. This implies that the crew of workers takes an average of 7 weeks to complete each road project.
