How do you graph an inequality on a number line?
Inequalities represent a range of values, rather than a single value.
Let's see some examples to understand better.
Let us consider the inequality
This would mean
This is represented by a line starting from
In case the inequality was
It would mean that
In case you can't draw on the number line, you can also show the range just above the number.
If your inequality is
You can represent it as:
Following are some great examples that I got from here.
