Xavier claims that the number of text messages he sends is proportional to the amount he owes on his monthly phone bill. He made a list of the number
of text messages he sent and the amount he owed for the first four months.
• January: 300 text messages sent; $15.00 owed
• February: 314 text messages sent: $15.70 owed
• March: 486 text messages sent; $24.30 owed
• April: 205 text messages sent: $10.25 owed
Which of the following methods would help Xavier prove his claim? Choose the TWO correct answers.
A
Xavier could plot data points based on the number of text messages sont in each month and the amount owed to create a straight line
on the graph starting at (0, 0.05).

B
С
Xavier could create a table listing the number of text messages sent in each of the months listed and the amount he owed for those
months to test for equivalent ratios.
