Solving One-Step Inequalities
Learning Objective
I can solve one-step inequalities and graph the solutions on a number line.
Key Concepts
When you multiply or divide both sides of an inequality by a negative number, you must swap the inequality sign.
To solve multi-step inequalities, you can use the distributive property and combine like terms to simplify each side before isolating the variable.
The solution to an inequality can be expressed using a number line, where an open circle indicates the endpoint is not included and a closed circle indicates that it is included in the solution.
