    Start with the graph of x. you know that the the graph is x is a line. You know that because: y = mx + b. Now, you have 3x + 13. and you know that b = y-coordinate. So that means you're shifting 3x UP by 13 units on the y-axis. Same with the 2nd function, it's a linear function. Except now you're not adding , your subtracting, meaning negative, shifting your line negatively on the y-axis.

    y = mx + b is the function for a LINE. |dw:1356778518146:dw| where m = slope b = y coordinate for instance, if I have 3x + 2 then your graph is: |dw:1356778594056:dw| it means 3 (x) + 2 2 is y so 2 shifted UP two. if it was -2, then I would of shifted the line DOWN two.
