Answer: The following table is proportional
Step-by-step explanation:
If you see closely, you can calculate the slope of the graph (y=Mx+b)
for the first values, the number of tickets is 5 and the cost is $40. Effectively, one ticket cost $8 (40/5). So, cou can plug this value in to the x values and check if it matches with the y- values. For sample, 10 tickets 10x8= $80, which matches the table. All these values work.
