2. Let me introduce myself I’m a line. This is where I spend most of my time on a graph. I
have many friends. I hope you like them just as much as I do.
3. My neighbors are the X-axis and Y-axis. The X-axis runs horizontally and the Y-axis runs
vertically. They are similar to number lines. The X- axis and Y- axis are very important in
plotting my points.
4. I’m made up of several points that are plotted on my graph. These points each have their
own X and Y component. Each point can be labeled as (x , y). Here A would be labeled
(1,1) and B as (2,3). Without my points I would not be a line.
5. I have a cool property known as my slope. My slope is equal to the change in y over the
change in x. Here my slope is 2/3. It is easier to think of my slope as rise over run. Start
at a point and count how many boxes on the Y-axis it takes to reach the next point. Then
count how many boxes it take to run to the point.
6. Graphing lines can tell you about many correlations. Such as the height of a ball after
you have thrown it. It is important to remember that all lines can be written in the
equation of y = mx + b.
