EX: (-1,3) , (2,5) , (0,0)

3. Graphs & Tables TABLE: WHY Graphs? A chart that shows ordered pairs.
Easy to see relationships.

4. Different Graphs Bar Graph Pie Chart Line Graph Comparing categories
Comparing parts of a whole
Line Graph
Comparing 2 things that change together
(most common in science!)

5. Lab #1 – “Introduction to Graphing Activity”
Measuring in Metrics:
Meter, cm, mm
INCHES

6. LAB #1 Vocabulary Review:
