Answer:
The artist would use diagonal lines, "zig zag" lines and hatched lines.
Step-by-step explanation:
If the artist wants to create a painting that expresses tension, he must use lines that promote an effect of stress, anxiety, fear and discomfort. The best lines to convey this impression are the diagonal lines (which convey the feeling of lack of stability and discomfort), "zig zag" lines (which convey the feeling of anxiety, restlessness and stress) and hatched lines (which can provide the feeling of fear, tension and worry).
