1. The Graphing World A 7th grade PowerPoint Presentation on learning to
Make coordinate graphs!

2. Definition
The definition of coordinate graph is showing the relationship between two variables.

3. The x-axis in a coordinate graph is the
horizontal line. This is the independent variable.
This means that the x-axis information
does not rely on the y-axis information.

4. The y-axis in a coordinate graph is the vertical line.
It is the dependant variable. This means that the y-axis information relies on the x-axis information.

5. Equal Intervals This interval is equal to the one above it.
Each Interval needs to be equal in order for you to plot. That is because if you do one that is one inch apart and one that is one centimeter apart it’ll look odd.
That’s what graph paper is for.

6. Labeling

Each axis needs a label in order for you to know what you are graphing.

7. Each graph needs a title to know what your graph is about.

Title: Jumping Jack Experiment
Each graph needs a title to know what your graph is about.

8. How to plot data
Plotted Point
When you start plotting, you first look on the x-axis and go to a number. Then you look on the y-axis and go to a number. Then you meet them and you put a point. You have now plotted. It’s important to always plot on graph paper.

10. How To Plot Step 1-Read Coordinates (example (5, 3))
Step 2-The first number should go on the X-axis, for example number 5 is your x-coordinate so you would move to your right 5 spaces.
Step 3-The second number should go on the Y-axis, for example number 3 is your y-coordinate so you would move up 3 spaces.
Step 4-After that, don’t forget where your points are. Once you have done step 2 and 3 you will follow the line your numbers are on and plot a point where they meet.

11. Labeling
To fully complete a coordinate graph, you need to make sure you have labeled everything.
This means a title, the x- and y-axis, data, and a summary (statement about what the graph is showing)
The Number of Books People Read in a Year 3
This graph shows the number of books people read increase through the years.

(Number of books) 2 1 1 2 3 4
X-axis (Number of years)

12. Remember To Check For:
T Title
L Labels
U Units
D Data
S Summary

13. In the bar graph above Apples are shown as 10, Pears are shown as 12, and Kiwi are shown as 3.

14. How many A’s? How many F’s? How many I’s?

15. How many Bob’s? How many Allie’s?
How many Ann’s?

16. Now it’s your turn to graph.
Graph the data shown in the box for #9 on p.19 in your textbook.
Use a ruler and pencil to neatly create your graph.
Make sure you label everything and answer the question.
