Chapter 2.6 McDougal Littell Middle School Math Course 1 Joseph Williams Melvin E. Sine Elementary [email_address] Objective : Plot points on coordinate grids and make line graphs.
Vocabulary Ordered Pair  – p. 83 -  two numbers used to find a coordinate on a coordinate grid.   Coordinates  – p. 83 -  the numbers in an ordered pair that locate a point on a coordinate grid.  Line Graph  – p. 84 -  a graph that represents data using points connected by line segments to show how quantities change over time.
Ordered Pair & Coordinates Ordered pairs look like  (2, 5). They are the coordinates of where a point is on a graph.  The first number (2)  tells you how far  RIGHT  you move. The second number (5) tells you how far  UP  you move.
Graphing Points Graph the following points on the grid. A (1, 0)  B (2, 9)  C (3, 6)  D (10, 5)
