Solve linear inequalities

Linear inequalities in one or two variables: practice and worksheets

Solve and graph linear inequalities in one or two variables, including compound constraints.

143 questions Foundation to advanced Grade 9

Concept overview

An inequality describes a range of values rather than a single solution. Its graph uses an open or closed boundary and shading to show every value that satisfies the condition.

Key points

  • Reverse the inequality sign when multiplying or dividing by a negative number.
  • Use a solid boundary for ≤ or ≥ and a dashed boundary for < or >.
  • Test a point to determine which side of a two-variable boundary to shade.

Worked example

Solving −3x + 2 > 11 gives −3x > 9 and therefore x < −3; the sign reverses when both sides are divided by −3.
