This document provides instructions for graphing linear equations. It begins with examples of solving linear equations algebraically. Students are then introduced to key properties of linear equations: they contain two variables and graph as straight lines. The document demonstrates graphing various linear equations by plotting their solution sets as points and connecting them with a straight line. It concludes by asking students to reflect on similarities and differences between the graphed linear equations.
