If the inequality is a “greater than” or “less than,” then the line itself is not included; the line is drawn as a dotted line, and only the shaded region is included in the inequality Take a look at some examples...A linear inequality looks just like a linear equation, except that an inequality sign replaces the equal sign They are graphed just as lines are graphed, except that the “greater than”
