Vector: how do I draw a straight line in a coordinate system?

Your x-axis is marked incorrectly, the line does not match the diagonal. This has nothing to do with cleanliness, as you can’t accurately determine the x value

you can row the different lengths x, y and z to each other, so that you come to the support vector step by step. The vector can thus also be visualized more graphically. You can also do the same with the direction vector
