Question

The quantities x and y are in a proportional relationship.

What do you know about the ratio of y to x for any point (x, y) on the line?

Answer 1

Answer: constant of proportionality

Explanation: Assuming that we have two proportional quantities; one is x and one is y. If you know whether the relationship between them is direct or inverse proportion, then the ratio of the two quantities y/x gives us a constant generally known as the constant of proportionality.
