Best ResponseYou've already chosen the best response.2Start 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 = ycoordinate. So that means you're shifting 3x UP by 13 units on the yaxis. 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 yaxis.

Best ResponseYou've already chosen the best response.2y = 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.
