1. The problem is to write down the coordinates, typically meaning to represent points in a plane or space using their coordinate values. 2. Coordinates are usually expressed as pairs or triplets of numbers separated by commas. For example, in 2D, a point is written as $(x,y)$ where $x$ is the horizontal position and $y$ is the vertical position. 3. In 3D, a point is written as $(x,y,z)$ where $x$ is horizontal, $y$ is vertical, and $z$ is depth. 4. Without specific points to write down, the general form is: - 2D coordinates: $(x,y)$ - 3D coordinates: $(x,y,z)$ 5. If you provide specific values or points, I can write down their coordinates explicitly.
