Given points $(x_1,y_1),(x_2,y_2),...(x_n,y_n)$ and lines of the form $y=a_1x+b_1, y=a_2x+b_2,...y=a_nx+b_n$ what is the curve such that the sum of the distance from all points and lines is equal to some constant? What are these curves called?

1For general points and lines, the curve would probably be called "nonexistent" or "empty". Consider, for instance, a tic-tac-toe board with unit spacing; if the constant is less than 2, then the set of solutions is empty. – John Hughes Aug 29 '15 at 15:40

If we agree to consider the sum of squares of the distances then the problem is workable. Otherwise one might be tempted to resort to Lagrange's multipliers. – Adelafif Aug 29 '15 at 15:45

@Adelafif what is that? – tox123 Aug 29 '15 at 21:15
