Paige visited the arcade last week. She kept track of the numbers of tokens she used to play a game and the number of tickets she earned for playing the game. Paige graphed this line that represents the relationship between the tokens she used to play the game and the tickets she earned. Does this line represent a proportional relationship between the two quantities? Explain your thinking. If Paige continued graphing the line, what would the y-coordinates be for the x-coordinates of 5 and 7? Explain using your knowledge of proportional relationships.
