End of Section
4

Congratulations. You've now reached the end of section 4. In this
section, you've learned about the Cartesian Plane, and how equations can be matched up with geometric shapes like points, by connecting equations to to the Cartesian Plan. You've
also been introduced to the skill of graphing, which lets you create graphs based on the value of variables. This is an important mathematical
skill.

At this point, I recommend that you go back and read through
this chapter a second time. You will probably find that, reading it through a
second time, you will learn more from each part, and gain a deeper
understanding of the concepts introduced in each part (see list below). As well, if you didn't
answer all of the questions, or do all of the exercises the first time around,
why not do them now?
