# 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

**Answer:**

`x<=3`
