Solving One-Step Inequalities
Learning Objective
I can solve and graph one-step inequalities on a number line.
Key Concepts
When solving inequalities, the steps are the same as solving equations, except if you multiply or divide by a negative number, you must reverse the inequality symbol.
When graphing inequalities, an open point uses a rounded parenthesis in interval notation, while a closed point uses a square bracket.
When using interval notation, we always use a rounded parenthesis on positive infinity or negative infinity.
