The SLANTING line also has to move since the SLANTING line is drawn with reference to X-axis and Y-axis to begin with, isn’t it? So, assuming the line is 45 degree slanting, the (x,y) values would be (1,1)(2,2)(3,3)(4,4) … etc. If the X and Y co-ordinates are rotated and if the SLANTING line is...

Suppose, if you have a SLANTING line (45 degree) in between X & Y axis and if you rotate the coordinates by 45 degrees would not (or should not) the SLANTING line also move by 45 degree? If the SLANTING line does not (or should not) move then I agree the X axis is the same as the SLANTING line.

All, I have to teach One Dimensional, Two Dimensional, and Three Dimensional Motions to my son and have been reading quite a bit on these topics. I still have a question and would be glad if someone can help me understand or point me in the right direction. I'm worried that I might be missing...
