Introduction to graphs

Introductory activity to graphs.
Activity 1. Move the points around, find their coordinates, check if your answers are corrrect Activity 2. Put all the points on the X-axis. Check their coordinates. Activity 3. Put all the points on the Y-axis. Check their coordinates. Activity 4. Allign points A, B, and C on a horizontal line. Draw the line that passes throught the 3 points. Look at the equation. Activity 5. Allign points D, E, and Fon a vertical line. Draw the line that passes throught the 3 points. Look at the equation. Activity 6. Allign points G, H, and I on a tilted line. Draw the line that passes throught the 3 points. Look at the equation. Activity 7. Compare the equation of the 3 lines. What are the conclusions you can make?
