Linear Inequality An inequality is an open mathematical sentence formed when an inequality symbol is placed between two expressions. Examples of inequalities: x < 3 x – 4 ≤ 5 x + 2 > 7 x ≥ 4
< Less Than ≤ Less than or Equal To > Greater Than ≥ Greater than or Equal to
The graph of a linear inequality is the graph on the real number line of all solutions of the inequality. Lets graph a simple inequality: x < 3 -4 -2 0 2 4 6 8 In words this says: all real numbers less than 3 Lets graph another: x ≥ 4 -4 -2 0 2 4 6 8 In words: all real numbers greater than or equal to 4
x < 6 x > -2 x ≤ 6 x < 0 x ≥ 6 4. 5. 3. 1. -4 -2 0 2 4 6 8 -4 -2 0 2 4 6 8 2. -4 -2 0 2 4 6 8 -4 -2 0 2 4 6 8 -4 -2 0 2 4 6 8 Your Turn Graph the following inequalities
