Question

What is the constant of proportionality in the equation y=5x

Answer 1

The const. of prop. is k = 5.

Explanation:

The equation y = 5x closely resembles the general equation for direct proportion: y = kx. k is the proportionality constant. Therefore, k = 5.

Answer 2

y = kx

k - constant of proportionality

y = 5x

k = 5
