What is the relationship between Hachures lines and the slope?

As the use of shading became systematized during the eighteenth and nineteenth centuries, French cartographers referred to these shading lines as “hachures.” Hachures represent the slope of the land—the more gentle the slope, the fewer the lines—and the absence of line indicates flat terrain.
