Linear Inequalities

Parameter questions for inequalities often require identifying the coefficient that produces a stated solution set.

Least you need to know

  • Multiplying or dividing by a negative number reverses the inequality sign.
  • A stated boundary value can be used to solve for the parameter.

Key notation

  • $x>-4$ — All values greater than -4

Worked example

  • Isolate the variable in terms of the parameter.
  • Match the resulting boundary and inequality direction.

Common mistakes

  • The inequality direction can reveal whether the parameter is positive or negative.

How to recognize it

  • The problem gives a solution set and asks for an unknown coefficient.
