Which statements are true about the graph? (choose 3)
Responses
A There is a proportional relationship between the number of notebooks and the cost because the x-value is always greater than the y-value.There is a proportional relationship between the number of notebooks and the cost because the x-value is always greater than the y-value.
B The point (1, 2.5) can be used to determine the total cost by subtracting 2.5 from the number of notebooks.The point (1, 2.5) can be used to determine the total cost by subtracting 2.5 from the number of notebooks.
C The point (1, 2.5) can be used to represent the unit rate of 2.5 dollars per notebook. The point (1, 2.5) can be used to represent the unit rate of 2.5 dollars per notebook.
