- Shift-drag: Hold down the
**shift**key, then drag the described object. - Control-drag: Hold down the
**control**key, then drag the described object. - Control-shift-drag: Hold down both the
**control**key and the**shift**key, then drag the described object. - <=>: One of the following relationships:
- less than
- less than or equal to
- equal to
- greater than or equal to
- greater than

- A filled dot () is the intersection of two lines, both with corresponding equations including the equality.
- An empty dot () is the intersection of two lines, one or both with corresponding equations not including the equality.

- Use the slider controls to change the following parameters:
**m**and**b**in the linear relation y <=>**m**x +**b**.**a**,**b**and**c**in the the linear relation**a**x +**b**y <=>**c**.**n**in the linear relation y <=>**n**.**n**in the linear relation x <=>**n**.

- Drag the slider thumb to change the value of a parameter. Use the
**up**and**down**arrow keys to increase or decrease the selected parameter. (Use the keys for fine adjustments.) - NOTE: If a key doesn't respond:
- position the cursor in the applet frame
- click the mouse button
- try the key again.

- Use the
**left**and**right**arrow keys to change the selected parameter. The selected parameter will have light blue slider gutters. - Drag a slider scale to change the range of the scale while maintaining the scale length.
- Drag a location in a slider gutter towards or away from the thumb to change both the range of the scale and the scale length.
- Select the corresponding parameter button to enter a value for a parameter.
- Select the
**PRECISION**button to set number rounding. - Select the
**TRACE**button to see if the corresponding cursor location is on the graph by using verification. - Select the
**RESET**button to restore the applet to the initial state.

- Drag the
**dot**along the y-axis to move the line. - Drag a location along the line other than the
**dot**to change the slope of the line.

- Adjust the line by changing the parameters. There are no methods available to adjust the graph in the graph area.

- Drag a location along the line to move the line.

- Shift-drag in the graph area to move the entire coordinate system.
- Control-drag in the graph area, towards or away from:
- the x-axis, to change the y-axis scale.
- the y-axis, to change the x-axis scale.

- Control-shift-drag in the graph area to see if the corresponding cursor location is on the graph by using verification.

- Press a number to make that linear inequality the currently selected one.
- Position the corsor in the graph area then press the "t" key. Pressing a number to make that linear inequality the currently selected one will display information about the cursor position in plane coordinates relative to the selected inequality.
- Use the "RESET" button to restore the applet to the initial state.
