Sal's goal in this video is to "familiarize ourselves with the x, y-coordinate plane." If your pupils have blank expressions when you present them with graphing problems, this video will be a great help to clear up the basics.

Using a number line can provide students with a concrete representation of the value various numbers hold. Sal plots six different numbers on a number line. He includes whole, decimal, and negative numbers.

So you've got some x-values and some y-values and you want to make a scatter plot. First thing is to make a table for your x and y values. Then make ordered pairs and you can plot them.
