Final answer:
The term for using coordinates to identify the position of a point is 'Coordinate geometry', which is built upon axes in a Cartesian grid system, expandable from 2D to 3D spaces.
Step-by-step explanation:
The term used to describe the use of coordinates to uniquely determine the position of a point is d) Coordinate geometry. The coordinate system is based on two perpendicular lines, known as axes. Points are determined on these axes using sets of numbers corresponding to their position. In a 2-dimensional space, these points are represented by x and y coordinates on a flat plane, creating a Cartesian grid. This system is named after René Descartes, and it can also be extended into three dimensions using an additional z coordinate. Coordinate geometry is essential in various applications including graphing on paper and extended to real-world mapping and navigation, such as with latitude and longitude on the Earth's surface.
