The Graph of a Linear Equation in Two Variables

This lesson explains how to graph a linear equation in two variables, using the example x + y = 8. It covers finding solutions, plotting them on a coordinate plane, and verifying that they form a straight line. The lesson concludes by emphasizing that any point on the line is a solution, and the line represents infinite solutions.
