1. COORDINATE PLANE
Math 7

2. What is the coordinate plane?
The coordinate plane is formed when a horizontal number line (x-axis) and a vertical number line (y-axis) are joined in the middle.
This middle point is called the origin.

3. What does it look like?

4. Quadrants
Drawing the axes separates the coordinate plane into quadrants.
The first quadrant (I) is located in the upper right. Then you go counter-clockwise to quadrant II, III, and IV.

5. Label the Quadrants and Axes

6. Ordered Pairs An ordered pair is a fancy name for a “point”
(x,y) is the format for an ordered pair
The x-coordinate is listed first and the y-coordinate is second

7. Graphing Ordered Pairs
To graph ordered pairs, you go left or right from the origin (on the x-axis) to the x-coordinate first
From the x-coordinate, you go up or down to the y-coordinate
Place the point here and label it with the ordered pair.

8. Plot the points, label, and tell which quadrant they are in.
(3,2)
(5,1)
(-3,4)
(-7,3)
(7,-5)
(-4,-3)
(3,-2)
(-6,-4)
(6,3)

9. Points that don’t lie in a quadrant
(2,0)
(-5,0)
(-7,0)
(6,0)
(0,3)
(0,-4)
(0,-7)
(0,5)
If they don’t lie in a quadrant, where do they lie?
