As shown in the figure, in the plane rectangular coordinate system, the endpoint coordinates of line AB are a (- 2,4), B (4,2), and the line y = kx-2 has an intersection with line AB, then the value of K cannot be () A. -5B. -2C. 3D. 5

As shown in the figure, in the plane rectangular coordinate system, the endpoint coordinates of line AB are a (- 2,4), B (4,2), and the line y = kx-2 has an intersection with line AB, then the value of K cannot be () A. -5B. -2C. 3D. 5

Substituting a (- 2,4) into y = kx-2, we can get 4 = - 2k-2, we can get k = - 3. When the line y = kx-2 has an intersection with line AB and passes through the second and fourth quadrants, we can get k ≤ - 3. Substituting B (4,2) into y = kx-2, we can get 4k-2, we can get k = 1
