In a 1-dimensional coordinate system, which of these is an example of an object's position?

A. west

B. south

C. (4, - 3)

D. 3 blocks east

The correct option is D. 3 block east

Explanation:

According to the coordinate system, one dimensional coordinate system is a coordinate system in which there is only one dimension (X). For example, in the option D, there is only one dimension whose value is 3.

According to the coordinate system, a two coordinate dimensional system is a coordinate system in which there are two dimensions (X, Y). For example, in the option C, there are two dimensions 4 and - 3.
