The four X's are supposed to be spaced out between the lines. You're supposed to match each model with it's expression. The regular line represents the variable

6. wolfgirl

variable expression*

7. nubeer

the x btween lines matches with 4x.. as u see there are x's and red line is above all of them so u have to add all 4 of them.. x+x+x+x = 4x

8. wolfgirl

Okay, thanks, now to figure out the rest of them

9. nubeer

ok good.. let me know if u need help

10. wolfgirl

thanks, its still a little a little hard to understand and I don't know how to do the other ones

11. nubeer

hmm just look on the information given to u.. and red line tells u what part u have to find..

12. wolfgirl

Is the first one x-4?

13. nubeer

hmm no look .|dw:1348839749754:dw| now look the above line u have to find the equation of that part.. now look below the middle line u see more then half is 4 and the rest is x. and u have to find the value of whole line so 4+x

14. wolfgirl

Ohhh so the first one is X/4?

15. nubeer

nooo.. u have to find the value of whole line half part is 4 and rest half is x.. to get the full line u have to add both

16. nubeer

you are talking about the first question in ur doc? right?

17. wolfgirl

Yeah, it's the same as the one I drew
