HELP 10 pts What is the constant of proportionality in the equation?

y = 5 x

A. 0

B. 1

C. 4

D. 5

Answer 1

D. 5

Explanation:

When an equation is written in the form:

`y=kx`, the constant of proportionality is
`k`.

The equation given to us is
`y=5x`

When we compare with
`y=kx`, we have:

`kx=5x`

This implies that:

`k=5`

Hence the constant of proportionality is 5.
