Mastering Inequalities with Desmos

The video tutorial covers how to use Desmos for solving SAT Math inequalities, including graphing individual inequalities and systems of inequalities. The instructor demonstrates plotting inequalities, setting graph windows, and using guess-and-check methods to find solutions. The tutorial also emphasizes the importance of identifying the correct shaded regions in systems of inequalities. The lesson concludes with a final example and encourages viewers to practice using Desmos for similar problems.

What does a dashed line on a graph in Desmos indicate?

• The graph is incorrectly plotted

• The points on the line are included in the solution

• The points on the line are not included in the solution

• The inequality is only valid on the line
