Question

The equation y = 5.5x represents a proportional relationship. What is the constant of proportionality?

1) 5.5
2) 15.5
3) 1
4) 5

Answer 1

The constant of proportionality in the equation y = 5.5x is 5.5, indicating a directly proportional relationship between y and x.

Step-by-step explanation:

In the equation y = 5.5x, which represents a directly proportional relationship between y and x, the constant of proportionality is the factor that relates y to x. When two variables are directly proportional, a change in one leads to the same change in the other. In this case, the constant of proportionality is 5.5, meaning that y changes by 5.5 times the change in x. If we were to plot this relationship on a graph, we would see a straight line passing through the origin (0, 0), which depicts this proportional relationship.
