The cost of mailing a package is proportional to the weight of the package. The proportional relationship can be represented with the equation c = 0.6w, where c represents the total cost and w represents weight in ounces. A graph for the equation is shown.
Which of the following statements is true about the graph shown?
The graph is incorrect and the line should go through the point (0.6, 1).
The x-axis and y-axis are labeled incorrectly.
The graph does not show a proportional relationship.
The equation c = 0.6w is correctly represented by the graph.
