## Real Graphs

#### Activity Overview

This lesson involves identifying patterns of data from given lists.

#### Objectives

• Students will explore the plots of various data sets, looking for patterns.
• Students will identify plots that appear to be functions.
• Students will determine which plots appear to form a linear pattern, and then acquire the best function that models the pattern, in the form of y = mx + b.
• Students will parse the linear function, looking at the slope and the y-intercept in the context of the data that was used. They will identify the units of these values and their contextual meaning.
• Students will use functions to model relationships between quantities.
