Key concepts students will learn:

  • When solving inequalities, if you multiply or divide by a negative number, you must reverse the inequality symbol.

  • The solution to an inequality can be expressed as an inequality, a graph on a number line, and using interval notation.

  • When using interval notation, we use a square bracket if the value is included in the interval and a rounded parenthesis if the value is not included in the interval.
