1. Section 5-1 Relating Graphs to Events SPI 22G: select the linear graphs that model the real-world situation SPI 22M: select the non-linear graph that models the real world situation SPI 23C: determine the domain and range of a function represented by the graph of real-world situation
Objectives:
Interpret, sketch, and analyze graphs
Graphs are used to show relationships between two variables.
Data shown can be interpreted as:
1. increasing slowly or quickly
2. decreasing slowly or quickly
3. remaining constant

2. Interpreting Graphs
When interpreting graphs:
Read the title of the graph
Read the labels of the x and y axis
This graph shows someone taking a walk in the neighborhood. Describe what it shows by labeling each part.

3. Interpreting Graphs
Which graph could show a car sitting at a stoplight?

4. Do you think this graph is a good model of a

Why or why not?

5. Interpreting Graphs
A pelican flies above the water searching for fish. Sketch a graph of its altitude from takeoff from shore to diving to the water to catch a fish. Label each section.

6. C A B A B C Interpreting Graphs
Suppose you pour water into each of the containers at a steady rate. Match each container with a graph that shows change in height of the liquid in the container over time. C A B A B C

7. Classwork Each student will sketch a graph.
Each student will exchange graphs with a partner.
Each student will write a situation for the graph and label it accordingly.
