A point on the real number line that is associated with a coordinate is called its graph. To construct a number line, draw a horizontal line with arrows on both ends to indicate that it continues without bound. Next, choose any point to represent the number zero; this point is called the origin. Figure 1.1.2 1.1. 2. The \bar and \overline commands. I want to represent, say, the closure of a set or the extended reals, e.g., $\bar {\mathbb {R}}$ but unfortunately this creates a bar that is much too small (horizontally) and can barely be seen.
