The constant of proportionality in the equation y=7x is 7.
In this context, the constant of proportionality means that for every 1 road project (x), it takes 7 weeks (y) for the crew of workers to complete all the projects. This implies that the rate at which the number of road projects is completed is constant at 7 projects per week.
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?
