Draw a graph to illustrate each of the following situations.

1. Prices are now rising more slowly than at any time during the last five years.
2. I really enjoy cold milk or hot milk, but I hate lukewarm milk!
3. The smaller the boxes are, then the more boxes we can load into the van.
4. After the concert there was a stunned silence. Then one person in the audience began to clap. Gradually those around her joined in and soon everyone was applauding and cheering.
5. If movie admissions are too low, then the owners will lose money. On the other hand, if they are too high, then few people will attend and again they will lose. A movie theater must therefore charge a moderate price in order to stay profitable.
