line
Linie and Strich can both refer to something drawn. Linie tends to emphasize a longer or continuous course, while Strich refers to a single, specific stroke made with a writing or drawing instrument. For a short, single mark, Strich is therefore usually more appropriate.

Mach neben dem ersten Punkt einen kurzen Strich.
Make a short stroke next to the first dot.
Zieh eine gerade Linie vom ersten Punkt bis zum letzten.
Draw a straight line from the first dot to the last.
