LESSON 1 Using Coordinates

Does your Mr. Origin look the same as this one? This Mr. Origin has a glove on his right hand. What is special about the right hand of your Mr. Origin?

We can use Mr. Origin to help describe where things are. We can draw a line through Mr. Origin that goes from left to right. We call that the left/right axis. (Mr. Origin's hands point in the directions of the left/right axis.) Mathematicians call it the x-axis.
