Inequalities and number lines

Inequalities can be represented on a number line.

And as we have already shown, inequalities can be represented by arrows too:

And a number line can ONLY mean a line with a number on it.

And to represent an equality equation on a number line read what the inequality expression says.

Examples

1. Represent x=2 on a number line

This reads x=2 ONLY

2.  On a number line represent

x>=2

This reads as x  is greater than OR equal to 2

3.  On a number line represent

x<=2

This reads as x is less than OR equal to 2

4.  On a number line represent

x>2

This reads x is greater than 2

5.  On a number line represent

x<2

This reads x is less than 2

Using the above examples will allow you to work out all future problems.

6.  Write down the inequality shown on the number line below

The circle above the 3 shows x is less than or equal to 3

x<=3
