Mastering Linear Inequalities and Graphing Techniques

The video tutorial covers solving linear inequalities, starting with an introduction and addressing technical issues. It explains solving inequalities with one and two variables, using number lines and coordinate planes. The tutorial demonstrates graphing inequalities, focusing on half planes, and provides examples using slope-intercept and standard forms, including the cover-up method.

What are the two forms of solving linear inequalities discussed in the introduction?

• One variable and four variables

• Two variables and three variables

• One variable and three variables

• One variable and two variables
