What to Focus On

  • An equation uses =.
  • An inequation uses <, >, ≤, ≥, or ≠.
  • < means is less than.

  • A linear inequation has the form ax + b > 0, ax + b < 0, ax + b ≥ 0, or ax + b ≤ 0.
  • The coefficient a must not be 0.
  • The variable x appears with power 1.

  • Replacement set means the set from which x is chosen.
  • Universal set is another name for replacement set.
  • Solution set means the values that satisfy the inequation.

Common Mistakes to Avoid

When multiplying or dividing an inequation by a negative number, the inequality sign stays the same.

The boundary number is always included in the solution set.

Any dark arrow on a number line means the solution is always all real numbers.
