Change the length of a line and keep same width?

Question

How do I resize a line without changing the width of the line in Inkscape?

Scenario: I have already drawn a horizontal line and want to make it longer. If I select the line, use the resize handle to the middle right and resize then the width of the line becomes larger as I drag to right to make the line longer. The Shift, Ctrl and Alt keyboard modifiers do not seem to have the desired effect either.

I have looked through the tutorials available from http://www.inkscape.org/doc/ and checked the Inkscape FAQ

Answer 1

On the far right side of the Tool Controls Bar, you'll find four buttons (to the right of the "Affect:" label; see the screenshot below). You can use those to control which aspects of an object are affected by, e.g. resizing operations.

Answer 2

Select the Edit Paths by Nodes tool and grab one end of the path. You can then move it around. If you're using freehand lines it's a bit more complicated but the principle is the same (you have to move multiple nodes).
