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 = 3\) is the graph made by coordinate points where \(x\) is equal to 3, for example (3, -4), (3, -3), (3,-2), (3, -1) and so on. The region which satisfies the inequalities is between these ...
