Please this home work do tomorrow please help

Well, I cannot make a model for you but, i can help the best I can! I will put an example line picture
4. The elevator would be -2 then would go up to 3 because - this sign would represent lower than on the integer line.
5. it would be 7 because we go up from -5 to 7 by counting 12 times
6. it goes from -20 to -35
Now I am confident in my answers but, I am only a middle schooler so, i'm not all "Yeah I 100% know what i'm talking about"
