Question

Y=3/8x describes a proportional relationship between x and y. What is the constant of proportionality?

Answer 1

The constant of proportionality k is 3/8

Explanation:

We are given
`y=(3)/(8)x` which describes a proportional relationship between x and y. We need to define constant of proportionality

If y ∝ x then

y=kx where k is constant of proportionality.

Comparing the given
`y=(3)/(8)x` with y=kx, we can find value of k i.e constant of proportionality.

So, k= 3/8

Hence, The constant of proportionality k is 3/8
