WebSolution to Problem 23.3. (a)A line with a rational slope is uniquely determined by its slope m and its y-intercept b. Hence the set of all lines with rational slopes is equivalent to f(m;b) : m 2Q;b 2Rg= Q R. Since R is uncountable and R ˇ(f0g R) Q R, Corollary 22.4 implies that … Webtheorem 1 Every line is of the following types: Rational slope no lattice points.
