An inequality is a mathematical statement that indicates the relative size or order of two values using symbols such as <, >, ≤, or ≥. Inequalities can be solved to find the range of values that satisfy the given conditions.

Inequalities can be represented graphically on a coordinate plane, with the solution region often being a shaded area.
When solving inequalities involving two variables, you may need to test points to determine which regions satisfy the inequality.
Nonlinear inequalities involve terms like quadratics ($x^2$), cubics ($x^3$), or other polynomial expressions.
Systems of inequalities consist of multiple inequalities that are considered simultaneously, and their solutions are typically found in overlapping regions on a graph.
The boundary line of an inequality can be solid (for ≤ or ≥) or dashed (for < or >), indicating whether points on the line are included in the solution set.
