# Graphs

In this lesson, you will create graphs. Mathematical representations enable mathematicians and scientists to visualize problems—and solutions to problems—in ways that help them further explore the mathematics of a situation. It also allows them to detect possible errors in their work, and to make generalizations based on specific quantities in a situation in order to gain a broader perspective on the relevant mathematics.

Look at the table about the temperature at the park in relationship to the time of day.

- You can make the relationship even more visible by representing it as a graph. Create a graph based on the table.
- How is the relationship visible in the graph?
