Giancarlo buys granola. The graph shows the relationship between the weight and the cost of the granola. Which of the following are true statements about the graph. Choose all the correct answers.

The point (8,24) means that 8 pounds will cost $24.

The point (1,3) means that the unit rate is $3 per pound of granola.

The point (4,12) means that it cost $4 for 12 pounds of granola.

Since the line passes through (1,3), 1/3 is the constant of proportionality.

The equation y = 3x represents the graphed relationship.

The graph is not a proportional relationship.
