Name the axis on which (0, 0, -6) lies.

Answer

To determine the axis on which the point (0, 0, -6) lies, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Coordinates**: The point given is (0, 0, -6). In a three-dimensional coordinate system, the coordinates are represented as (x, y, z). Here, x = 0, y = 0, and z = -6.

2. **Identify the Axes**: In a three-dimensional coordinate system, there are three axes:
- The x-axis (horizontal axis)
- The y-axis (vertical axis)
- The z-axis (depth axis)

3. **Analyze the Coordinates**:
- Since both x and y are equal to 0, this means that the point does not extend along the x-axis or y-axis.
- The z-coordinate is -6, which indicates that the point is located 6 units below the origin along the z-axis.

4. **Locate the Point**:
- The coordinates (0, 0, -6) imply that the point lies directly on the z-axis, specifically at a position of -6 units from the origin.

5. **Conclusion**: Therefore, the point (0, 0, -6) lies on the z-axis.

### Final Answer:
The point (0, 0, -6) lies on the z-axis.
