Let's look again at our airplane, but this time with it taking off. Specifically, look at the change in height or altitude (rise) and thechange in distance (run).

The x, y coordinates for the plane just as it leaves the ground are (0,0).  The plane ascends to an altitude of 40 meters each second (rise) while it travels across the runway at a distance of 50 meters each second (run). To create the graph of this take off, follow these steps.

1. Fill in the remaining points of the data table. Click each column heading to check your answers.

2. Set up the graph paper. Use intervals of 50 meters for the x-axis and 40 meters for the y-axis.
3. Plot the points from the table onto the graph.
4. Try to draw a straight line that comes close to the points. This is called a best-fit line.

Now check your work by clicking Answer to see the graph.
