When presented with an inequality graph and a set of possible inequalities, follow these steps to determine the correct match ...

Inequalities that use < or > symbols are plotted with a dashed line to show that the line is not included in the region. Inequalities that use ≤ or ≥ symbols are plotted with a solid line to show that ...

Plotting graphs of inequalities works almost exactly the same way as plotting graphs. Simple inequality graphs can be plotted parallel to the \(x\) or \(y\) axes and tables of values can help to plot ...

The trichotomy property and order relation symbols show the Cartesian plane divided into three regions, as students connect tabular and graphical representations of functions.
