Hy im having problem solving one problem with derivates i think. I have two points and im looking for closest summed distance point on line. two points are T1(-1, 2) and T2(1,6) and line is very simple y = x.

Originally Posted by PJani Thank you it helped...what about other more extended functions y = k*x +n? what about them? same procedure, but instead of (x,x) on the line y = x, you'll have (x, kx+n) on the line y = kx+n
