##### How to use

*Enter* values for the coordinates
*x*_{1},
*y*_{1}, and
*z*_{1} (for the point *P*) and
*x*_{2},
*y*_{2}, and
*z*_{2} (for the point *Q*) into the
corresponding text input fields.
__Example__:
*P*=(1,-2,2), *Q*=(3,2,4)

*Click* the "Graph" button
(this button also refreshes the graph).

*To erase* the graph and all input fields, click the
"Clear" button.

##### Examples

*P*=(1,-2,2), *Q*=(3,2,4)

__Points only__
__Include line segment__

__Include vector__

##### Other Notes

The point *P* and its coordinate box are drawn
in blue.
The point *Q* and its coordinate box are drawn
in green.
The line segment between *P* and *Q* and the
