Chapter 13.9, Problem 2BE

To determine

To find: On which axis or axes does point $(0,0,-9)$ lie.

Answer to Problem 2BE

The point $(0,0,-9)$ lies on z-axis.

Explanation of Solution

Given information: Point $(0,0,-9)$ .

Calculations:

At z-axis, x-coordinate and y-coordinate are 0.

Here at point $(0,0,-9)$ , x and y coordinate are 0.

So, point $(0,0,-9)$ will lies on z-axis.

Hence, the point $(0,0,-9)$ lies on z-axis.
