The independent variable is m (number of miles) and the dependent variable is e (the cost).
Step-by-step explanation:
In this situation, if you were to graph the equation on the number line ,
M will be the x and e will be the y.And we know most of the time that x is independent in that situations and y is dependent.
The cost of depends on how many miles travelled.If the cost will go up it depends on how many miles.
