Lesson Narrative
The purpose of this lesson is to introduce students to the graphical interpretation of multiple equations written in the form . The equations arise in the context of distance and time in order to anchor student understanding of the shared solution as the point in time when distances are equal. Students are also introduced to a pair of situations represented by the same equation to illustrate how situations can arise with infinitely many solutions.
- Create a graph that represents two linear relationships in context, and interpret (orally and in writing) the point of intersection.
- Interpret (orally and in writing) points that lie on one, both, or neither line on a graph of two simultaneous equations in context.
- Interpret a graph representing equivalent equations in context.
Let’s use lines to think about situations.
