CHAPTER 4
SECTION 4.1
Solving Linear Inequalities
MINI LESSON
Solving Linear Inequalities
Solving a linear inequality is similar to solving a linear equation.
You can add, subtract, multiply, or divide both sides by the same number.
If you multiply or divide both sides by a negative number, you must reverse the inequality symbol.
The solution to an inequality is often a range of values shown on a number line.
Question 1
What is the solution to the inequality \(2m - 4 \le 3(2m + 4)\)?
Question 2
Which graph is the solution to the inequality \(6.4 - 4x \ge -2.8\)?
