Having trouble with this one help appreciated
Hoochie [10]

Answer:

The constant of proportionality is 3.50.

Step-by-step explanation:

We know that when y directly varies with x, such that

y=kx

The number 'k' is called the constant of proportionality.

Given the equation

y=3.50x

as

y=kx

so

k=3.50           ∵ y=kx

Here the value of k = 3.50, which is the constant of proportionality.

Therefore, the constant of proportionality is 3.50.
