In the Nemeth course errata, there are instances in which the student is directed to move expressions to the right (indent) to show that the expressions are displayed.

The Nemeth Code (Sec. 188a.) states that an expression is displayed if it is “set apart from the body of the text by skipped lines, indentation, or some other means.”

In the following example, the distance formula would have fit on the previous line, but the author placed the equation on its own line. Would this be considered “set apart” although it is not indented?

Example:

Draw a line segment between the two points on the coordinate grid: (-5,9) and (-9,-6).

To find the distance between two points, use

d=√((x_(2 )-x_1 )^2+〖(y_(2 )-y_1)〗^2 ).
