Question

The Cartesian Coordinate System
The Cartesian coordinate system is a system that tells you your exact position on a graph. Why
Is this useful? It is useful because you can use this system to graph a series of points that will
provide solutions to your equations. The equations that are used with this system will have two
variables, one for each axis.
The Cartesian coordinate system uses a horizontal axis that is called the x-axis and a vertical
axis called the y-axis. Equations for lines in this system will have both the x and y variable. For
example, the equation 2x + y 2 is an example of a line in this system. Lots of equations can be
written with these two variables. You can have equations that explain population growth and you
can have equations that explain your cell phone bill.
What does a Cartesian coordinate system look like? It looks like graph paper with a dark line for
the x-axis and another dark line for the yaxis. These two axes cross perpendicular to each other.
The point where they cross is at point o for each axis. This graph extends forever in all directions.
Both axes are labeled with numbers according to the number line.
You can think of the x-axis as a horizontal number line and the y-axis as a vertical number line.
When you draw one, though, you only draw it as big as you need it to be. If you only need the x-axis
and the yaxis to go up to 10, then you can stop there for both axes. Let's look at some examples to
see how it works. Let's start with points,​
