The abscissa of points a and B are a and B (a ＞ 0, B ＞ 0) on the image of the first-order function y = x and y = 8x respectively. If the line AB is the image of the first-order function y = KX + m, when Ba is an integer? Find the value of integer k satisfying the condition

The abscissa of points a and B are a and B (a ＞ 0, B ＞ 0) on the image of the first-order function y = x and y = 8x respectively. If the line AB is the image of the first-order function y = KX + m, when Ba is an integer? Find the value of integer k satisfying the condition

Let a (a, a), B (B, 8b), then there is AK + M = ABC + M = ABC + M = 8b, and the elimination of M is: (a-b) k = a-8b: (a-b) k = a-8b, (a-b) k = a-8b, (a-b) when a = B, when a = B, a = b = 0 is not consistent with the meaning of the title, and {a ≠ B, and K = a (a, a) a (a, a, a, a (a, a, a), B (a) and K = a (a) and K = a {8ba} 8t1 {8t1 − 8t1} t = 8t1 t1} t − t} t = 8t = 8t − 8t {8t1} t = 8t} 8t} 8t} 8t − 8t b > 0, T-1 ≠ 0 , t is an integer, and t ＞ 0, t ≠ 1; and ∵ K is an integer, ∵ T-1 = 7 or T-1 = 1, ∵ t = 8 or T = 2, ∵ k = 9 or K = 15
