Try for yourself before you read much further to construct configurations of points in the plane that determine “relatively few” slopes. For this we assume, of course, that the n > 3 points do not all lie on one line. Recall from Chapter 9 on “Lines in the plane” the theorem of Erdös and de Bruijn: the n points will determine at least n different lines. But of course many of these lines may be parallel, and thus determine the same slope.
