1. Objective The student will be able to:
1) identify each quadrant as I, II, III or IV
2) graph ordered pairs on a coordinate plane
3) identify which quadrant an ordered pair
fall in.

2. Ordered pairs are used to locate points in a coordinate plane.
y-axis (vertical axis) 5 -5 5
x-axis (horizontal axis) -5
origin (0,0)

3. In an ordered pair, the first number is the x-coordinate
In an ordered pair, the first number is the x-coordinate. The second number is the y-coordinate. Graph. (-3, 2) 5 • -5 5 -5

4. What is the ordered pair for A?5
(3, 1)
(1, 3)
(-3, 1)
(3, -1)
• A -5 5 -5

5. What is the ordered pair for B?
(3, 2)
(-2, 3)
(-3, -2)
(3, -2) 5 -5 5
• B -5

6. What is the ordered pair for C?
(0, -4)
(-4, 0)
(0, 4)
(4, 0) 5 -5 5
• C -5

7. What is the ordered pair for D?
(-1, -6)
(-6, -1)
(-6, 1)
(6, -1) 5 -5 5
• D -5

8. Write the ordered pairs that name points A, B, C, and D.5
A = (1, 3)
B = (3, -2)
C = (0, -4)
D = (-6, -1)
• A -5 5
• D
• B
• C -5

9. The x-axis and y-axis separate the coordinate plane into four regions, called quadrants.II
(-, +) I
(+, +)
III
(-, -) IV
(+, -)

10. Name the quadrant in which each point is located (-5, 4)II
III IV
None – x-axis
None – y-axis

11. Name the quadrant in which each point is located (-2, -7)II
III IV
None – x-axis
None – y-axis

12. Name the quadrant in which each point is located (0, 3)II
III IV
None – x-axis
None – y-axis

13. Answers
(-5, 4) is in quadrant II
(-2, -7) is in quadrant III
(0, 3) is in quadrant 1
