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’.

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.
