Answer 1

The graph that represents the passages that are above 6 meters in elevation would be:

A number line with an open circle at positive 6 and a shaded arrow to the right.

This indicates that the elevations above 6 meters are included (with the open circle representing that 6 is not included, hence only above 6 is shaded).
