HOW TO USE THIS APPLET

Constructors Invisible : Grid Invisible

• Drag the intersection location ( • ) to move both lines.
• Drag any other location on either line to rotate the lines about the intersection location.

Constructors Visible : Grid Invisible

• Drag the intersection location ( • ) to move both lines.
• Drag any other location on either line to rotate the lines about the intersection location.
• Click (and hold down) the mouse button in any triangle to see how the slope value is determined.
• Drag any location along the circle to change the slope determining triangles.
• Drag any intersection location of the circle and lines ( • or • ) to change the slope determining triangles as well as rotate the lines about the intersection location.
• THE CONTROL KEY : Click and drag in the graph area towards or away from the intersection location ( • ) to change the scale. [Try to use "good" scale values (shown in applet when this operation takes place).]

Constructors Invisible : Grid Visible

• Drag the intersection location ( • ) to move both lines.
• Drag any other location on either line to rotate the lines about the intersection location.
• THE SHIFT KEY : Click and drag in the graph area to move the entire coordinate system.
• THE CONTROL KEY : Click and drag in the graph area towards or away from the origin to change the x and y axis scale. [Try to use "good" scale values (shown in applet when this operation takes place).]
