1. SWBAT… review / learn the Cartesian Coordinate System Agenda 1. Warm-Up (5 min) 2. Brain Pop Video – Cartesian Coordinate System (10 min) 3. Practice problems on the white boards (30 min) Warm-Up 1. Write the homework in your planners for the week 2. Set up Cornell Notes in your notebook: Title is “Cartesian Coordinate System” HW1: Cartesian Coordinate System (back of this week’s agenda) Monday, 11/29/10

2. Brain Pop Video (quiz at the end of the video) Take notes in your notebooks on anything you didn’t know or didn’t remember

3. On the white board with the coordinate system: Label the x- and y-axis Label the origin Label Quadrant I, II, III, IV

4. Coordinate Plane Parts of a plane 1. x-axis 2. y-axis 3. Origin 4. Quadrants I-IV x-axis y-axis Origin ( 0, 0 ) QUAD IQUAD II QUAD IIIQUAD IV

5. On the white board with the coordinate system: Label the below points: A (3, -4) B (5, 6.5) C (-4, 5) D (-7, 0) E (0, -4) F (0, 0) G (0, π)

6. Plotting Points 1. Remember when plotting points you always start at the origin. 2. Next you go left (if x-coordinate is negative) or right (if x-coordinate is positive. 3. Then you go up (if y-coordinate is positive) or down (if y-coordinate is negative) Plot these 4 points: A (3, -4) B (5, 6.5) C (-4, 5) D (-7, 0) E (0, -4) F (0, 0) A B C DF E

7. A Coordinate System The horizontal line or x-axis is known as the _____.

8. Reminder! Take notes in your notebooks on anything you didn’t know or didn’t remember

9. A Coordinate System The vertical line or y-axis is known as the ______. Hint 1: Begins with “o”

10. A Coordinate System The point at which the axes meet or intersect is known as the _____.

11. A Coordinate System A coordinate system has ___ quadrants.

12. A Coordinate System Any point P is represented by an _______ of numbers written in the form (x, y)

13. A Coordinate System The x-value is always ______ and the y-value is always second.

14. When a point is plotted on the coordinate system, a _______ (positive or negative) x value indicates a movement to the left. A _______ (positive or negative) y value indicates a movement down.

15. When a point is plotted on the coordinate system, a _______ (positive or negative) x value indicates a movement to the right. A _______ (positive or negative) y value indicates a movement up.

17. Daniela plotted the coordinates of the 2 largest toy shops in the city. The coordinates of Shop A are (2,6). The coordinates of Shop B are in Quadrant II with the same y- coordinate as Shop A. What are the coordinates of Shop B? A. (2,0) B. (3,6) C. (4,−6) D. (−5,6)

18. 1. Place a point anywhere in the first quadrant. 2. Place another point anywhere in the second quadrant. 3. Place another point anywhere in the third quadrant. 4. Place another point anywhere in the fourth quadrant. 5. Trade white boards with the person next to you. 6. You have to label the 4 ordered pairs.

19. Get Ready for Chapter 3 #13: Solve for y: 3x + y = 1 Answer: y = -3x + 1 #15: Solve for y: 5x – 2y = 12 Answer: y = 5/2x – 6 #17. Solve for y: 3 – 1/2y = 5x Answer: y = -10x + 6
