Math Problem Statement

What does k represent in the equation y = kx?

Solution

The correct answer to the question "What does kk represent in the equation y=kxy = kx?" is:

1) Constant of proportionality

In the equation y=kxy = kx, kk is the constant of proportionality, which determines the rate at which yy changes in relation to xx. It means that yy is directly proportional to xx, and kk scales xx to give yy.
