Final answer:
In this problem, the vectors can be characterized by the coordinate system they belong to: Cartesian coordinate system.
Step-by-step explanation:
In this problem, the vectors shown can be characterized by the coordinate system they belong to.
a. When a vector is vertically upward in the coordinate system, it is aligned with the positive y-axis in a Cartesian coordinate system.
b. When a vector is vertically downward in the coordinate system, it is aligned with the negative y-axis in a Cartesian coordinate system.
c. When a vector is horizontally to the right side of the coordinate system, it is aligned with the positive x-axis in a Cartesian coordinate system.
d. When a vector is horizontally to the left side of the coordinate system, it is aligned with the negative x-axis in a Cartesian coordinate system.
