Matt called a cab company and asked to be picked up two blocks south of dupont circle in washington, dc. which concept best represents the type of information matt gave to the cab company? relative location coordinates absolute location line of longitude

relative location

Explanation:

Relative location refers to the location of something according to the position of a landmark or other locations, so it always needs another place as a point of reference. In Matt's case, he uses the Dupont Circle as a reference.

The rest of the choices are incorrect because coordinates involve latitude and longitude position numbers that indicate absolute location; and lines of longitude are imaginary vertical lines called Meridians, which link points with the same longitude from the North to the South Poles.
