Module 4 topic 1 part 1 notes
- 1. Module 4 Topic 1 The Coordinate Plane (Part 1) Midpoint Formula Relations & Functions
- 2. Vocabulary x-axis y-axis Origin Quadrants I, II, III, IV Ordered Pair Rene’ Descartes 1596-1650 “ I think; therefore I am.”
- 3. The x-axis is the Horizontal Axis. The y-axis is the Vertical Axis.
- 4. The Origin is the Center of the Coordinate Plane . Its Ordered Pair is (0, 0).
- 5. Notice how a Coordinate Plane is made up of 4 squares? These sections of squares are called Quadrants . They are numbered: I, II, III, IV
- 6. Quadrant I (+,+) Quadrant II (-,+) Quadrant III (-,-) Quadrant IV (+,+) Question: What Quadrant does (-5, 3) lie? Answer: Quadrant II
- 7. Graphing Ordered Pairs What are the coordinates of Point B? What are the coordinates of Point A? (-5, -7) (7, -2)
- 8. Click on the below link to practice these concepts. The Coordinate Plane Game
- 9. Now that you have the concept of The Coordinate Plane Go to the next Power Point presentation to begin instructional notes on The Midpoint Formula
