Question

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

Answer 1

the equation represents direct variation

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

⇒ y = 5 /7 x → k = 5/ 7

Explanation:

Answer 2

5/4

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
