1.  In mathematics, we use a grid to locate points.

2. The coordinate plane is formed by the perpendicular intersection of two number lines called axes.

3. Horizontal axis is called the x-axis

4. Vertical axis is called the y-axis

5. The intersection of the two axes is called the origin

6. The intersection of the two number lines forms four quadrants.

7. Divides into Four Quadrants I

8. Divides into Four Quadrants I II

9. Divides into Four Quadrants I II III

10. Divides into Four Quadrants I II III IV

11. Divides into Four Quadrants and… I II III IV

12. Math Alert The quadrants do not include the axes I II III IV

13. Math Alert A point on the x or y axis is not in a quadrant I II III IV

14. Each point in the coordinate plane is associated with an ordered pair, (x,y) (x,y)

15. The x and y of the ordered pair, (x,y), are called its coordinates (x,y)

16. Math Alert There is an infinite amount of points in the Cartesian plane

18.  Always start at (0,0)---every point “originates” at the origin

19.  In plotting (x,y) ---remember the directions of both the x and y axis y x

20.  ( x,---) x-axis goes left and right

21.  ( ---, y ) y-axis goes up and down

24.  Start at (0,0)  (, ---)  Move right 2 +

25.  (---, )  (---, 1)  Move up 1 +

28.  Start at (0,0)  (, ---)  Move right 4 +

29.  (---, )  (---, -2)  Move down 2 -

32.  Start at (0,0) (, ---)  Move left 3 -

33.  (---, )  (---, 5)  Move up 5 +

36.  Start at (0,0)  (none,---)  No move right or left

37.  (0, )  (---, 4)  Move up 4 +

40.  Start at (0,0)  (,---)  Move left 5

41.  ( ---, 0)  No move up or down
