Inequalities that use ≤ or ≥ symbols are plotted with a solid line to show that the line is included in the region. For example, this graph shows the inequality \(x \textless -1\). This can be ...

x \neq 5 \) reads as ‘\(x\) is not equal to 5.’ Show the inequality \(x \textless 2\) on a number line. \(x\) is less than (<) 2, which means an open circle at 2 must be used. \(x\) is less ...
