Flipping The Inequality Sign
Solve and graph Flipping The Inequality Sign in Grade 9 algebra. Understand when to flip the inequality sign and how to represent solution sets on a number line.
Key Concepts
Property Remember to change the direction of the inequality symbol when multiplying or dividing both sides by a negative number. Explanation When you multiply or divide both sides by a negative number, you're flipping the values to the opposite side of the number line. To keep the statement true, the inequality sign must do a flip too! Forgetting this is like walking backward without looking—you'll end up in the wrong place! So, remember: negative multiplier equals sign flipper! Examples $ 4x 24 \implies x < 6$ $15 5x \le 40 \implies 5x \le 25 \implies x \ge 5$.
