Hello @AKazak,

[Here](https://community.deeplearning.ai/t/c1w1-lab04-why-arent-the-gradients-perpendicular-to-the-contour-lines-solved/590511/5) is a similar discussion that shows that if we skew the axes, the path will not be perpendicular.

If we look at the axes’ scales, it is obvious that (1) the w axis is longer than the b axis, but (2) the range of w is smaller than that of b. Therefore, before we say that it is not perpendicular, we would need to correct such effect first.

Cheers,  
Raymond
