7. Knowing the Graph Grid

Understanding the Graph Paper



Reading Scales










Graph Plotting

For clarity in illustration, ink is used in this 'demonstration'.
You should use a sharp pencil, and ruler to plot your graph. Always get ready an eraser to clean off any irrelevant markings.

Step 1: How do we decide where to place the axes?

• Do you "know" the graph paper?
• What would you make reference to?

Step 2: Scale matters!

• The numbers on the axes must be clearly marked.
• The scale should be written on the top right corner of the graph paper.

Step 3: Let's start plotting!

• Mark the points clearly with "X"
• Join the points with a straight line (use a long ruler!)
• The line should be drawn within the given domain
