A point on x-axis which is equidistant from the points (5, 4) and (- 2, 3) is

(a) (2,0)    (b) (3,0)    (c) (6, 0)    (d) (7, 0)

The value of ‘k’ so that the points (7, - 2), (5, 1) and (3, k) are collinear :

(a) 3    (b) 4    (c) 5    (d) 6

343.

For what value of ‘k’ the points A(1, 5), B(k, 1)andC(4, 11) are collinear?

(a) k = 1    (b) k = 2    (c) k = - 1    (d) k = - 2
