What is the constant of proportionality in the equation y = 5/4x

5/4

Step-by-step explanation:

Given the equation y = 5/4x this relationship is an inverse proportionality i. e the y variable is inversely proportional to x.

Mathematically y = k/x where k is the proportionality constant.

Comparing y = 5/4x with y = k/x, the constant of proportionality k in he function y = 5/4x is 5/4

the equation represents direct variation

∙ y = k x ← k is the constant of variation

⇒ y = 5 / 7 x → k = 5 / 7
