It is the first.
5 minutes, $0.85
10 minutes, $1.10
The units should be the same for the x and for the y
Typically the x is independent and known. We know minutes. The y is the dependent variable and depends upon what the x is. The cost depends upon the minutes. This is by convention, however.
The answer is the first.
