## Lesson: Finding and Graphing Points for Linear Relationships

Developing the Concept

At this level, students will begin to see the relationship between equations and straight-line graphs on a coordinate grid.

At this level, students will begin to see the relationship between equations and straight-line graphs on a coordinate grid.

**Materials: ** poster paper or a transparency and overhead projector for demonstration; straightedge; Coordinate Grid Worksheet (PDF file), a straightedge, and lined paper for each student

**Preparation: ** Draw a coordinate grid on poster paper or a transparency. Label the *x-* and *y-axes* from 0 through 10. Make copies of the Coordinate Grid Worksheet (PDF file) for students, or use Learning Tool 51 in the *Learning Tools Folder.*

**Prerequisite Skills and Concepts:** Students should know about ordered pairs and locating points on a grid. They should also be able to recognize and interpret an equation.

**Wrap-Up and Assessment Hints**

These skills will need lots of practice. Reinforce the need for students to work carefully so their graph is accurate. When you assess students' progress, keep the number of exercises small enough that they have time to complete each step without rushing.
