Answer:

Option C. 2

Explanation:

Let

x ----> the number of days

y ----> the internet charges in dollars

we have


y=2x

This is a proportional relationship between the variables x and y

The slope of the linear function is equal to the constant of proportionality k


k=m=2(\$)/(day)

The unit rate is the same that the slope

so

The unit rate is $2 per day

therefore

The unit rate in the equation is 2
