1. Graphing Basics

2. Creating a graph Draw the y-axis on the vertical axis and the X-axis on the horizontal one Label what variable is on each of the axis and show units

3. Title graph using format y vs. x Time (s) Distance vs. Time Distance (m)

4. Decide on what intervals you will be using on each axis and write those in Be sure that the intervals are even and appropriate to the measurements you have taken John’s Weight vs. Year

5. Draw the line of best fit (trend line)  A line on a scatter plot which can be drawn near the points to more clearly show the trend between two sets of data. Line of Best Fit Plot the data points that you collected on the graph (Scatter plot)

6. You try!! Draw a line of best fit for the following scatter plot. 1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 8 9

7. Plotting Points (x, y) (x, y) (3, 2) (5, 3) (3, -2) (-4, 1) (0,-1) (-3, -5)

8. Interpreting Graphs How many total miles did the car travel?
