Algebraic inequalities (inequalities with variables) are useful for describing real-world situations. Learn how to write inequalities and graph them on the number line.
A solution to an inequality makes that inequality true. Learn how to test if a certain value of a variable makes an inequality true.
Practice plugging in values to inequalities and checking to see if the inequalities hold true.
Learn how to graph an inequality on a number line to indicate which values make it true.
Learn how to plot a simple inequality on a number line. The example used in this video is x < 4.
Practice writing equations of inequalities graphed on number lines. Identify number line graphs of inequalities.
Learn how to write inequalities to model real-world situation.
Practice writing inequalities with variables to describe real-world situations.
