II. Create a horizontal line in Sketchpad.

Open Sketchpad
1.Select
>Graph
>Show Grid
and a Cartesian Coordinate graph appears.

2.Select the point tool and make two points on the x-axis of the graph. It doesn't matter which numbers you choose as long as the points are ON the x-axis.

Note: It might be easier to select the x-axis and y-axis and
>Display
>Hide axis
and then create the horizontal line from the two points you created.

3. Select the line tool.

4. Create a line by selecting each point that was created from step 2.
You have a horizontal line. Try to move the line.

5.Hide the grid.
>Graph
>Hide Grid

6. Hide the axes.
Select the Selection Arrow Tool.

Select the x-axis and the y-axis.
>Display
>Hide axis
It may be a little tricky selecting the x-axis since the horizontal line is covering the axis. If Display says Hide line rather than axis, try selecting it again. Now we have a horizontal line.
If you hide both the axis and line, just create another line as long as those two points you created on the x-axis are still there.
