On a separate page, sketch a graph of the equation in 3-space.

Suppose you are observing the coordinate system as shown below.

graph of a right-handed coordinate system shown with the first octant in the foreground.

If your graph represents a solid (opaque) wall, can you see the point ?

Which of the following is your graph (note that by clicking on any graph you will get a larger image)?
