How to graph linear inequalities

The video tutorial explains how to graph linear inequalities by first graphing the corresponding linear equation. It covers converting equations to slope-intercept form, determining if boundary lines are dashed or solid based on inequality signs, and using test points to decide shading. Key points include flipping the inequality sign when multiplying or dividing by a negative number and using 0,0 as a test point unless the line passes through it.
