Inequalities are the relationships between two expressions which are not equal to one another. The symbols used for inequalities are <, >, ≤, ≥ and ≠. \(7 \textgreater x\) reads as '7 is ...

x \leq -4\) reads as '\(x\) is less than or equal to -4' (or '-4 is greater than or equal to \(x\)', reading from right to left). Show the inequality \(y \textless 2\) on a number line.
