Solving One-Step Linear Inequalities in One Variable

This video tutorial covers solving one-step linear inequalities in one variable. It explains how to express solutions as inequalities, graphs, and using interval notation. The tutorial provides examples of different inequalities and demonstrates how to solve them, emphasizing the importance of reversing the inequality symbol when multiplying or dividing by a negative number.

What is the primary goal of the lesson?

• To solve quadratic equations

• To solve one-step linear inequalities

• To understand complex numbers

• To learn about polynomial functions

What must you do to the inequality symbol when you multiply or divide both sides of an inequality by a negative number?

• Change it to an equal sign

• Reverse it

• Remove it

• Keep it the same

What is the result of dividing both sides of the inequality -2 < 4 by -2?

• 1 < -2

• -1 > 2

• -1 < 2

• 1 > -2

Why do we reverse the inequality symbol when multiplying or dividing by a negative number?

• Because it makes the inequality easier to solve

• Because negative numbers are always less than positive numbers

• Because it is a rule in algebra

• Because it changes the direction of the inequality
