Determine whether the graph represents a proportional relationship. (4 points) A graph is shown. The x-axis is labeled from 0 to 9. The y-axis is labeled from 0 to 17. Four points are shown on the graph on ordered pairs 0, 4 and 2, 8 and 3, 12 and 4, 16. These points are joined by a line. The label on the x-axis is Number of boats. The title on the y-axis is Number of passengers. a Yes, it is a proportional relationship because the graph goes through the origin b No, it is not a proportional relationship because the graph does not go through the origin c Yes, it is a proportional relationship because the graph is a straight line d No, it is not a proportional relationship because the graph is not a straight line
