A: An independent variable could be how long she works. (Well it's not really independent I guess... Sorta depends.) A dependent variable could be how much money she makes, depending on how long she works.
B: Umm, like: (1, 7) If 1 was how many hours she worked and $7 is how much money she made, and therefore x would be how many hours she worked and y would be how much total money she made. (2, 14) (3, 21)
