**Anonymous**, Saturday, April 12, 2008 at 12:08amHi:

The equation x=4 refers to all ordered pairs whose x value is 4. Thus, for example, (4,o), (4,1), (4,2), etc. all satisfy the given equation. Notice that the three ordered pairs above fall on the vertical line passing through 4 on the x-axis. Indeed, all ordered pairs on such vertical line have x coordinate =4.

Regards,

Rich B.
