3. Warm Up Answers A (-6,-3) Q III B (3, -5) Q IV C (6, -3) Q IV
D (5, 1) Q I
E (7, 5) Q I
F (2, 4 ) Q I
G (-5, 1) Q II
H (-8, 5) Q II

4. Remember
You can graph points on the coordinate plane. A point has two coordinates which form an ordered pair.
The x coordinate tells how far to move left or right along the x- axis.
(-2, 6)
The y coordinate tells how far to move up or down along the y-axis.

5. The x axis is the horizontal number line.
It is formed by a negative number line (left of the origin) and a positive number line (right of the origin). x

6. The y axis is the vertical number line.
It is formed by a negative number line (below the origin) and a positive number line (above the origin). x

7. Plot (-3, 4) on a coordinate plane.
Example 1
Plot (-3, 4) on a coordinate plane.
To plot (-3, 4), start at the origin (0, 0). The x coordinate is -3 so move 3 units left on the x axis. x

8. Example 1
Plot (-3, 4) on a coordinate plane.
The y coordinate is positive 4 so move 4 units up from the x coordinate (-3).
Plot the point. x

9. Start at the origin. Go over 5 places right.
Example 2
Plot (5, -6) on the coordinate plane.
Start at the origin. Go over 5 places right.
Go down 6 places. x
Plot the point.

10. Move 6 spaces left and then go up 0 spaces.
Example 3
Plot the point (-6, 0) on the a coordinate plane.
Start at the origin.
Move 6 spaces left and then go up 0 spaces.
Plot the point. x

11. Move 3 places left and then go up 2 and a 𝟏 𝟐 places.
Plot the point (-3, 2 𝟏 𝟐 ) on the coordinate plane.
Example 4
Start at the origin.
Move 3 places left and then go up 2 and a 𝟏 𝟐 places.
Plot the point. x

12. A (5, 1) B (-3, 8) C (0, -6) D (-2, -9) E (4 𝟏 𝟐 , -2) F (7, 0)
Practice
Plot the points on the coordinate plane.
A (5, 1) B (-3, 8)
C (0, -6) D (-2, -9)
E (4 𝟏 𝟐 , -2) F (7, 0)

13. B A F E C D

14. Closure
Explain to a student who was absent how to graph the ordered pair (-1, 6).
