they say you are not supposed to answer people's homework. but, I guess these could be questions you are asking on your own accord for personal knowledge. so let me take a guess...

for one, id say C could definitely be right, but im not sure
2, price is shown on the vertical axis, and quantity on the horizontal, so the answer is D
3,D makes cents for that one
4,B, reduced quantity demaned at each price level
5,A, production technology is a determinant of supply and thus improvements in technology will result in a greater quantity supplied at each price
6,A, a subsitute is a replacement
7,C, complements are used together
8,most likely C
9, C, decrease, shift to the left as they are complementary goods

I changed one, I noticed that I did something stupid. 8 is most definitely C, sorry
