Answer: Yes Step-by-step explanation: Remember in order for the rates to be proportional it has to have a constant rate of change and it has to go through the origin if graphed For one this has a constant rate of change which is 3 dollars per 25 messages Now we just have to find out if it would go through the origin (0,0) To do so we subtract 3 dollars and then 25 messages 6-3=3 50 - 25 =25 then again 25-25=0 3-3=0 concluding that (0,0) is a solution Thus meaning that this is a proportional relationship
