Thanks YCC.

Can you help on these two as well?  

- Suppose you have a lemonade stand, and when you charge $1 per cup of lemonade
aide you sell 60 cups.  But when you raise your price to $2 you only sell 30
cups.
Write an equation for the number of cups you sell as a function of the price you
charge.  Denote "C" for number of cups, and "P" for the price you charge.
Assume the function is linear.

 

- Take a look at the table below and write out an equation for f(x).

x    -2 -1 0 1 2
f(x) -5 -2 1 4 7
