1. Solving Linear Inequalities
linear inequality: _________________________________ ________________________________________________ solution of a linear inequality: ______________________

2. Determine whether the ordered pair is a solution of the inequality. 1
Determine whether the ordered pair is a solution of the inequality. 1. (–2, 4); y < 2x (3, 1); y > x – 4

3. Determine whether the ordered pair is a solution of the inequality. 3
Determine whether the ordered pair is a solution of the inequality. 3. (4, 5); y < x (1, 1); y > x – 7

4. Because there are an infinite number of solutions to a linear inequality, we need to graph the linear inequality to show all of the solutions.
