For more advanced students, a graph is displayed.
For example, the inequality $3 - 2x \le 5x + 1$
is optionally accompanied by the
graph of $\,y = 3 - 2x\,$ (the left side of the inequality, dashed green)
and the graph of
$\,y = 5x + 1\,$ (the right side of the inequality, solid purple).
In this example, you are finding the values of $\,x\,$ where the green
graph lies on or below the purple graph.
Click the “show/hide graph” button if you prefer not to see the graph.
