  1. 9.01 – HDW define the relationships between two variables on a graph Do Now: Graph the following points: (4, 5) (-2, 3) (-3, -4) (3, -6)

  2. Exam Missed Who still needs to take it

  3. Goals of today • Graph points • Coordinate plane • How do graphs tell a story

  4. Drawing the C.P. Use a Ruler Label Axis Set scale Label Points

  5. Points in the coordinate plane are indicated with ordered pairs (x,y) Think: (↔, ↕) Examples: (4, 5) (-2, 3) (-3, -4) (3, -6) (0, 0)

  6. The coordinate plane Points in the coordinate plane are indicated with ordered pairs (x,y) (4,5) (-2,3) Examples: (4, 5) (-2, 3) (-3, -4) (3, -6) (-3, -4) (3, -6)

  7. The Four Quadrants y II I (+,+) (-,+) x IV III (-,-) (+,-)

  8. Graphing Stories • Stairs One • Stairs two • Running • Distance from Home Will probably just do two of them

  9. Now let’s just talk not write • Tell the story of each graph

  10. Now Tell the Story Scan here

  11. Describe the Relationship between x and y. Scan here

  12. Describe the Relationship between x and y. Scan here

  13. Describe the Relationship between x and y.

  14. Summary • Positive Change(“increasing”) • Negative change (“decreasing”) • Zero Change • Undefined Change

  15. Oh Canada…

  16. 8. Homework – Bonus Practice Where is the Earth’s x-axis? Where is the Earth’s y-axis? Where is our school’s coordinate? Challenge Where is the Earth’s x-axis? Where is the Earth’s y-axis? Where is our school’s coordinate?
