1. Coordinate Plane

2. Essential Question
Describe how to move, or plot points, on a coordinate plane.

3. What is a Coordinate Plane?
You may often hear a coordinate plane called a coordinate grid. By either name, the definition is the same:
A coordinate plane is formed when the x-axis meets the y-axis.

4. The X-axis The x-axis runs side to side, or horizontally.
Remember, we studied the x-axis when we created and read bar graphs and line graphs.

5. The Y-axis The y-axis runs up and down, or vertically.
Remember, we studied the y-axis when we created and read bar graphs and line graphs.

6. The Origin
The origin is the point where the two axes (x and y) cross each other.
The origin is always labeled 0 on the coordinate plane.

7. Moving on a Coordinate Plane
To move on a coordinate grid you need coordinate pairs.
A coordinate pair consists of two numbers, such as (4, 1)
The first number in the pair tells x-axis movement, and the second number in the pair tells the y-axis movement.

8. Moving on a Coordinate Plane
You will always move across first, then up or down last.
What are the coordinates for the fly on this coordinate plane?
Right! (4, 3)

11. Your Turn!
Using the provided coordinate grid, practice plotting the following coordinates:
A= (3,1) F= (4,0)
B= (2,5) G= (6,3)
C= (0,6)
D= (1,4)
E= (5,2)

14. Quadrants We have been working in Quadrant 1 of the coordinate plane.
However, since both x-axis and the y-axis are lines that never end, when they cross 4 Quadrants are formed.

15. X- and Y-Axes
Both the x- and y-axes contain positive and negative numbers.
The x-axis contains these numbers as shown:
Positive numbers are to the right of the origin, and negative numbers are to the left of the origin. -3 -2 -1 1 2 3

16. X- and Y-Axes
The y-axis contains both positive and negative numbers as shown. 3 2 1 -1 -2 -3

17. Quadrants When the two axes meet, 4 quadrants are formed.
Quadrant 1: (positive, positive)
Quadrant 2: (negative, positive)
Quadrant 3: (negative, negative)
Quadrant 4: (positive, negative)

18. What are the coordinates?

19. Your Turn Plot the coordinates on the coordinate grid:
A= (4,2) F= (-2,0)
B= (-3,3) G= (5,5)
C= (-1,-2) H= (-3,-5)
D= (2,-1) I= (1,-3)
E= (0,4)
