**Graph a Linear Relationship.**

Noah put $40 on his fare card. Every time he rides public transportation, $2.50 is subtracted from the amount available on his card.

(1). How much money, in dollars, is available on his card after he takes 0 rides?

(2). How much money, in dollars, is available on his card after he takes 1 ride?

(3). How much money, in dollars, is available on his card after he takes 2 rides?

(4). How much money, in dollars, is available on his card after he takes rides?

(5). Graph the relationship between amount of money on the card and number of rides.

(1). How many rides can Noah take before the card runs out of money?

(1). Where do you see this number of rides on your graph?
