#### Answer

The ordered triple represented by point C is $(-4,5,-6)$
To plot the point D $(5,-4,6)$ on the graph, we can move 5 units in the +x-direction, 4 units in the -y direction, and 6 units in the +z-direction.
We can see point D on the graph.

#### Work Step by Step

On the graph in the book, we can see that point C is reached by moving 4 units in the -x direction, 5 units in the +y direction, and 6 units in the -z direction.
The ordered triple represented by point C is $(-4,5,-6)$
To plot the point D $(5,-4,6)$ on the graph, we can move 5 units in the +x-direction, 4 units in the -y direction, and 6 units in the +z-direction.
We can see point D on the graph.
