  3. Example 3-4b Objective Graph points on a coordinate plane

  4. Example 3-4b Vocabulary Coordinate plane Two number lines that form right angles and intersect at their zero points

  5. Example 3-4b Vocabulary Coordinate grid Two number lines that form right angles and intersect at their zero points (coordinate plane)

  6. Example 3-4b Vocabulary x-axis The horizontal number line x-axis

  7. Example 3-4b Vocabulary y-axis The vertical number line y-axis

  8. Example 3-4b Vocabulary Origin The point of intersection of the two number lines origin

  9. Example 3-4b Vocabulary Ordered pair Any point on the coordinate plane graphed using two numbers (x, y) (3, 2)

  10. Example 3-4b Vocabulary x-coordinate The first number in the ordered pair (abscissa) (3, 2)

  11. Example 3-4b Vocabulary y-coordinate The second number in the ordered pair (ordinate) (3, 2)

  12. Example 3-4b Vocabulary Quadrant The number lines separate the coordinate plane into four sections II I IV III

  13. Lesson 3 Contents Example 1Name an Ordered Pair Example 2Graph an Ordered Pair Example 3Identify Quadrants Example 4Identify Quadrants

  14. Example 3-1a Name the ordered pair for point R graphed below. R Start at the origin. Move left to find the x-coordinate of point R, which is –2. Move up to find the y-coordinate, which is 4. Answer: R (–2, 4) 1/4

  15. Example 3-1b Name the ordered pair for point M graphed below. Answer: M (3, –1) 1/4

  16. Example 3-2a Answer: Graph and label the point M (3, 5) M (3, 5). Use a coordinate plane graph Write the point and coordinate pair above the graph M (3, 5) Begin at origin Using your pencil point, move 3 units to the right (do not draw a line) Move 5 units up. Draw a dot at the intersection Label dot with letter and coordinate pair 2/4

  17. Example 3-2b Graph and label the point G(–2, –4) Answer: 2/4

  18. Example 3-3a GEOGRAPHYUse the map of Utah shown below. In which quadrant is Vernal located? Locate axis of coordinate plane I Determine quadrants II Locate Vernal IV Identify quadrant where Vernal is located III Answer: Quadrant I 3/4

  19. Example 3-3b GEOGRAPHYUse the map of Utah shown below. In which quadrant is Tremonton located? Answer: Quadrant II 3/4

  20. Example 3-4a Name a city from the map of Utah shown below that is located in quadrant IV. Locate axis of coordinate plane I Determine quadrants II Locate city in quadrant IV IV Answer: Bluff III 4/4

  21. Example 3-4b * Name a city from the map of Utah shown below that is located in III. Answer: Cedar City 4/4
