1. Characteristics of Linear Graphs

2. Vocabulary ZERO: Where the graph crosses the X-Axis
Y-INTERCEPT: Where the graph crosses the Y-Axis
END BEHAVIOR: Does the graph Increase or decrease at the ‘ends’ of the graph (what do the arrows do?)

3. Example Zero:________ Y-Intercept:_________ End Behavior:

6. Domain The set containing all of the x-values.
*When finding the domain of a graph, ask yourself these 2 questions:
1.) What is the left-most point of this graph?
2.) What is the right-most point of this graph?

7. Range The set containing all of the y-values.
*When finding the range of a graph, ask yourself these 2 questions:
1.) What is the highest point of this graph?
2.) What is the lowest point of this graph?

8. Example
Domain:________________
Range:__________________

9. Example
Domain:________________
Range:__________________

11. Increasing & Decreasing
MOVE LEFT TO RIGHT
If your finger goes UP, the graph is increasing.
If your finger goes DOWN, the graph is decreasing.
If your finger goes neither up or down…then the graph is CONSTANT.

12. Example
Increasing or Decreasing?
