An inequation is made up of constants and variables, just like an equation but the major difference would be in the representation of the sign. An equation consists of the ‘equality’ sign, but an inequation consists of the ‘greater than’ or ‘lesser than’ signs. Graph inequalities calculator is the quick online tool which can make graphing inequalities easy and simple.

Example 1: On a number line, graph the inequation x ≥ 2 and shade the appropriate region.

                                  Given inequation: x ≥ 2
The above inequation means that ‘x’ includes the entire portion that covers the region which is greater than ‘2’.




The above shaded region represents the inequation x ≥ 2, since to the right side of ‘2’ there are numbers greater than ‘2’.
The solution in interval notation is   [2, ∞)



Example 2: On a number line, graph the inequation x < -1 and shade the appropriate region.
                                                         Given inequation: x < -1
The above inequation means that ‘x’ includes the entire portion that covers the region which is lesser than ‘-1’ without including ‘-1’ itself.



The above shaded region represents the inequation x < -1, since to the left side of ‘-1’ there are numbers lesser than ‘-1’

The shaded portion does not include ‘-1’ since it only says x < -1.

The solution in interval notation is   (-∞, -1)
