Interpreting Relationships with Line Graphs on a Coordinate Plane

The lesson teaches how to interpret relationships in data by creating line graphs on a coordinate plane. It uses the example of Bobby and Dan's typing errors to demonstrate graphing ordered pairs and analyzing patterns. The lesson explains how line graphs can change direction based on data relationships and emphasizes understanding these changes.

How do the increases in errors differ between Bobby and Dan based on the ordered pairs?

What does the graph indicate about the relationship between Bobby's and Dan's errors over time?
