Which system utilizes two linear coordinates?

The rectangular coordination system is defined by two linear coordinates, typically referred to as the x-coordinate and the y-coordinate. This system is used to define the position of a point in a two-dimensional space where the distances from two perpendicular axes (often representing width and height) are measured. The concept is foundational in mathematics and is extensively applied in various fields including physics and engineering for plotting graphs, mapping locations, and solving geometric problems.

In contrast, the polar coordinate system uses a radial distance and an angle to define a point's location, which does not involve two linear coordinates in the traditional sense. The geographical information system and geodetic system also do not primarily operate with a simple two-linear coordinate structure as they encompass more complex data management and representation. Thus, the rectangular coordination system stands out for its use of two linear coordinates, making it the correct choice in this context.
