See Fig 4. Soon after Suzan With a Z decided that she wanted even more pencils. Her friends were back to giving her 2 pencils and her enemies were taking 2. However, her friends were already getting suspicious so she decided to target her teacher. This anonymous teacher was pretty easy to please so all Suzan With a Z had to do was clean the classroom. In reward, her teacher gave her 2 more pencils. As a result of the gain of a couple pencils, Suzan With a Z realized that her linear equation moved up.
See Fig 5. After her teacher gave her the two other pencils, the teacher decided to inspect the “clean” classroom. They soon realized that all Suzan With a Z did to “clean” the classroom was shove everything under his desk. This teacher got pretty angry and decided to punish Suzan With a Z. They decided to take back the 4 pencils he had given Suzan With a Z. He ambushed Suzan With a Z and took back those pencils. Suzan With a Z, who was distraught from her lost pencils, realized that her linear relation just moved down.
See Fig 6. A week later it was Suzan With a Z’s birthday!!!!! As a gift, her teacher decided to give her back 2 pencils. Unfortunately, this was the day that her friends found out about all those pencils that she had previously “borrowed”. They got mad and began to take all the pencils that they could from her (took 2 pencils each). Her enemies felt bad and decided to return the pencils that they had previously taken. They each gave her 2 pencils. Strangely as Suzan With a Z looked at her linear relation she discovered that it was pointing in another direction.
Currently, Suzan with a Z has 3 friends. Her 4th kind of drifted away but was still friendly to her (which is considered ½ of a friend). She decided to graph this situation so she used Interpolation to figure out how many pencils she could get if she had 3 ½ friends. However, just as she was graphing her ½ a friend 3 more new people approached her. These people were incredibly friendly and nice and decided to become her friend. This made the ½ a friend jealous and that ½ a friend became 1 whole friend. Soon Suzan With a Z had a total of 8 friends that she gladly took pencils from. She wanted to graph this strange situation but she didn’t have enough graph space so she decided to use Extrapolation. See Fig 7 - cartoon (right)
