Question

Make sure it is the correct answer!!!!!!!!!

Identify the constant of proportionality in the equation.

y = 2.5 x


x

2.5

y

2.5x

Answer 1

For this case we have by definition, if "y" varies directly with "x", then it is true that:

`y = kx`

Where:

k: It is the constant of proportionality

We have the following equation:

`y = 2.5x`

So, as mentioned above we have to:

`k = 2.5`

Answer:

`k = 2.5`

Option B
