Cartesian Coordinates

The purpose of this lab is to help you fix in your mind the basic
features
of a "Cartesian Coordinate System" including the location of a point
with
given coordinates and the use of endpoint coordinates to determine the
length and slope of a line segment.
For the activities in this lab, you will be plotting points using
our
"Graph Explorer" applet,

but it will also be useful for you to do at least some of the
activities
"by hand" using a pencil and paper, so you might want to have some
graph
paper available before you start.(You may also want to try doing the
same
thing with your graphing calculator if you have one, or with any other
computer algebra system that you might have available on your
computer.)

(Either of the two buttons above can be used to
start
the lab in a new browser window on top of this one. The button on the
left
will run the lab in a framed window with the instructions in one frame
and the Graph Explorer in the other, and the one on the right will open
a window with just the instructions and a link to the Graph Explorer
which
will open it in another window. If you want to be able to reposition
the
text and graphs independently use the right button, but if you prefer
to
have the two parts kept together without having to manage the two
windows
yourself, then use the left button.)
