You have seen that graphs and tables can reveal information about a real-life situation.

Today, you will create stories and graphs and justify that they represent the same

situations.

Part 1:

Every morning, Gabriela

walks along a straight street

from her home to a bus stop,

a distance of 160 meters.

This graph shows her journey

on one particular day.

• What does the y-intercept

tell you about Gabriela’s

journey?

• What does it mean when the line

changes direction at !=50? What

does it mean whenit changes

direction at !=70?

• How fast is Gabriela walking in each section of the graph?

Interval: ____________________ Interval: ____________________ |
Speed: ___________________ Speed: ___________________ |

• Are her speeds possible? Why or why not?

• Would it make sense for the domain of the graph to include negative values of x? Why

or why not?

Time”in”Seconds”

Distance”from”Home”in”Meters”

Use your answers about the graph to write a story describing what may have happened on

Gabriela’s walk to the bus stop. Include specific details about time, distance, and speed.
