Best ResponseYou've already chosen the best response.0ok so they're asking you how many songs she will have after x weeks, in slope intercept form

Best ResponseYou've already chosen the best response.0they're giving you the slope  which is the rate of change each unit (in this case a week)

Best ResponseYou've already chosen the best response.0from the information given, we know that "m" is "5" in the y=mx+b slope intercept equation  i.e. each week (unity on the xaxsis), 5 songes are added.

Best ResponseYou've already chosen the best response.0so after four weeks, y (the number of songs) is 42, and we know the number of songs added each week was 5  so really we just need the constant  the number of songs that kelli started with

Best ResponseYou've already chosen the best response.0so y = mx +b, 42 = 5*4 +b

Best ResponseYou've already chosen the best response.0so kellie started with 22 songs on the mp4 player (the constant), and adds 5 songs each week. the slope intercept equations is hence y= 5*x + 22
