For the given table The distance traveled will depend on the number of hours.
So, the hours will be the independent variable ⇒⇒⇒ x-axis
and the distance traveled will be the dependent variable ⇒⇒ y-axis
While the hours is varied from 1 to 8, the best increments will be 1
and while the most of distance traveled is divisible by 5, the increment is 5
So, the correct answer is option (4)
x-axis: hours in increments of 1; y-axis: miles in increments of 5
