What is the definition for Inequality?

•  

  the relationship between two values showing if one is less than, greater than, or simply not equal to another value. (<, >, ≤ or ≥)

   

   

   

• a function that represents a straight line on the coordinate plane.

• a mathematical expression in which two expressions are compared using the inequality symbol. Almost the same as a linear equation, except the equals sign is replaced with an inequality.

• the set of two or more linear inequalities involving the same variables x and y.
