  3. You have already used ordered pairs to name and locate points. (Lesson 1–4) • Graph points on a coordinate plane. • Graph algebraic relationships. Then/Now

  4. quadrants Vocabulary

  5. Recall…we discussed the 4 Quadrants earlier in the year. Today, we will work with all 4 Quadrants. Y-axis Quadrant II (-,+) Quadrant I (+,+) X-axis Quadrant III (-,-) Quadrant IV (+,-) Origin (0,0) I give you the Coordinate Plane (we need graph paper now)

  6. Write Ordered Pairs A. Write the ordered pair that names point P. The x-coordinate is 4. The y-coordinate is –2. Answer: The ordered pair is (4, –2). Example 1

  7. Write Ordered Pairs B. Write the ordered pair that names point Q. The x-coordinate is –3. The y-coordinate is –1. Answer: The ordered pair is (–3, –1). Example 1

  8. A B C D A. Write the ordered pair that names point M. A. (2, 3) B. (–3, –2) C. (–2, –3) D. (–3, 2) Example 1

  9. A B C D B. Write the ordered pair that names point N. A. (4, –1) B. (4, 1) C. (1, –4) D. (–1, 4) Example 1

  10. Graph Points and Name the Quadrant A. Graph and label S(–1, –5) on a coordinate plane. Name the quadrant in which the point lies. Start at the origin. Move 1 unit left. Then move 5 units down and draw a dot. Answer: Point S is in Quadrant III. Example 2

  11. Graph Points and Name the Quadrant B. Graph and label U(–2, 3) on a coordinate plane. Name the quadrant in which the point lies. Start at the origin. Move 2 units left. Then move 3 units up and draw a dot. Answer: Point U is in Quadrant II. Example 2

  12. A B C D A. Graph and label A(3, –4) on a coordinate plane. Name the quadrant in which the point lies. A. Quadrant I B. Quadrant II C. Quadrant III D. Quadrant IV Example 2

  13. A B C D B. Graph and label B(–2, 1) on a coordinate plane. Name the quadrant in which the point lies. A. Quadrant I B. Quadrant II C. Quadrant III D. Quadrant IV Example 2

  14. Graph an Algebraic Relationship GAMES Mrs. Gossell’s class is playing a classroom quiz game. The difference between Ali’s and Joachim’s scores is 3 points. If x represents Ali’s score and y represents Joachim’s score, make a table of possible values for x and y. Then graph the ordered pairs and describe the graph. First, make a table. Choose values for x and y that have a difference of 3. Example 3

  15. Graph an Algebraic Relationship Then graph the ordered pairs on a coordinate plane. Example 3

  16. Graph an Algebraic Relationship Answer:The points in the graph are on a line that slants upward to the right. The line crosses the y-axis at y = –3. Example 3

  17. A B C D A.B. C.D. A. The sum of two integers is 3. If x represents the first integer and y represents the second integer, make a table of possible values for x and y. Example 3
