@sveinntryggva You are correct if you are thinking that the value of y $10 bills is equal to trice as many $5 bills-- but that is not what we are talking about here. Sal has it right for describing points we are indifferent between: the line he drew was y=10-2x. At x=0,y=10 you have $50, and you also have $50 at (2,9), (4,8), etc. with a slope of -2, willing to trade 2 x for 1 y.
In 4:22 I thought he said "Raichu's" when he said "Right Shoes",
lol.

I'm afraid graph no2 is incorrect. Y=10$bills; x=5$ bills
= y=2x would be the right function, but your plot suggests that 0 units of 10$ bills equals 2 units of 5$ bills. That would be a poor tradeoff :)
