In math, you'll learn about the Cartesian Coodinate System, which is a graphical method of showing
(x,y) points. The x and y axes cross at x=0 and y=0, or (0,0), which is called the origin. X-values extend
in the positive direction toward the right, and negative values are toward the left. Y-values extend positive
upward, and negative downward.

You can practice seeing where (x,y) points fall using this lesson. The two `line`

statements in the code box will draw the x and y axes. Try plotting some points using the `pset`

function, as in
`pset(5,5)`

or `pset(-30,20)`

. Use a lot of `pset`

statement to better understanding where points of a given (x,y) pair will
appear.

`pset(x,y)`

.
