Module 4 topic 1 part 1 notes

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