Answer:
The cost per package depends on the weight of the package.

Generally we consider the values on the y-axis or the vertical axis as the dependent values because they are dependent upon the x-value or the value on the horizontal axis.
Here from the graph we may observe that the cost of the package depends on the weight of the package.
