Question

The unit rate of the proportional relationship y= 2x is

Answer 1

We have that the unit rate is 2 [Option B].

***Explanation***

We have that a proportional relationship is characterized for having the form:

`a=kb`

Here a and b are the values that are proportional to one another and k is the constant of proportionality.

In our case we are given:

`y=2x`

Here x & y are the proportional values and 2 is the constant of proportionality.

And, from properties of division, we have that:

`(2)/(1)=2`
