## Topic outline

- The line in the Cartesian plane
**A line doesn’t have ends and it always goes to the same direction: it is straight, it has not curves**

** and always go to the same point.**

**Let’s use a small letter like r, for example, to name lines.**

**You can draw a line different orientation: it can be horizontal, vertical or orizontal.**

- Lines, segmentes and rays intro
- Two-variable linear equations and their graphs
- Graphs of linear equations
- Graphic
- The line in the Cartesian plane

This is a quiz on the line in the cartesian plan.
