Asketch of the line 2y-x=4 is shown. the line cross with the axes at a and b. calculate the coordinates of a and b you.

 solution a, e M, is uniquely defined by the inequality (A'an – f', '' – an) < 0 ... Vane M, x, e M. (6.1.9) It is possible because a, e X, and a € X, Since M, C M for all n > 1, the sequence {a}} is compact, hence, there exists ¥ € M such that a' – 30 as n ... M = {a e X | p(x) = 0}, where b : X → R is a convex and continuous functional.
