1. The Coordinate Plane Goal: Plot points on a coordinate plane.

2. The Coordinate Plane has… A vertical number line called the “y-axis” A Horizontal number line called the x-axis. An Origin

3. Identify the Origin with a green dot

4. Identify the x-axis with a blue line

5. Identify the y-axis with a red line

6. Ordered Pairs Each point on a coordinate plane corresponds to a ordered pair. The first number is the x-coordinate The second is the y-coordinate Written as (x,y)

7. Examples A (2,1) B C D (-2,-4) (-5,3) (4,-2)

8. You try it! A B C D

9. Plot the point (3,2) with a pink dot

10. Plot the point (-2,-3) with a orange dot

11. Quadrants The four regions on a coordinate plane are called “quadrants” I II III IV

12. Use the signs to find the Quadrant (P,P) = (P,N) = (N,P) = (N,N) = Hint III IIIIV Quadrant I Quadrant IV Quadrant II Quadrant III

13. You try it! Place a point in Quadrant I

14. You try it! Place a point in Quadrant 3

15. You try it! Place a point in Quadrant 4

16. You try it! Place a point in Quadrant 2

17. Summary Coordinate planes have an x-axis, y-axis, and an origin Points on a Coordinate plane are identified with an ordered pair. (x,y) The Coordinate plane has four regions called “quadrants”
