## Lesson: Finding and Graphing Points for Linear Relationships

Introducing the Concept

Your students may have encountered ordered pairs last year, but it's a good idea to start by reviewing the basic skills of locating on a grid a point from an ordered pair. A day spent using grids to practice locating points that fall in a straight line will be a day well spent.

**Materials:** poster paper or a transparency and overhead projector for demonstration; straightedge

**Preparation:** Draw a large coordinate grid on the poster paper or transparency. Label the *x- *and *y-axes * from 0 through 10. Display the grid where students can see it.

**Prerequisite Skills and Concepts:** Students should know about ordered pairs and locating points on a grid.
