The graph of the interval (-4,10) is simply the shaded region from -4 to 10 on the number line. Notice how parenthesis are used, so this means that we must use open circles at the endpoints



So here's what the graph looks like:

note: the open circles at -4 and 10 tell us to exclude -4 and 10 from the solution set.
