Intro to 3D Equations

What does the graph of x=2 look like when viewed on a number line (Singular Dimension)?

What does the graph of x=2 look like when viewed in the Cartesian plane?

What does the graph of x=2 look like when viewed in 3 dimensions?

What does the graph of look like when viewed in the Cartesian plane?

Describe the graph of .

The last two graphs you described are created in the Cartesian plane, in other words, they are 2-dimensional. What do the same graphs look like when examined in 3 dimensions? Make your conjectures and test them using the applet below.
