When plotting on a coordinate plane you always "run before you jump" so you would have the -2 stay because down would be the jumping portion and in this you would be falling down 4 and it is four so it would turn into zero.
Umm...not sure what your question is, but to make 10 cookies you would need 1.25 sticks of butter, and to make 48 cookies you would need 6 sticks of butter. Hope this helps!
