If the value of `k`, is the points `(k, 2-2k)`, `(1-k, 2k)` and `(-4-k, 6-2 k)` are collinear.

For what value of k are the points (k,2-2k) (-k +1,2k ) and (-4-k,62k) are collinear?

For what value of k are the points (k,2-2k)(-k+1,2k) and (-4-k,6-2k) are collinear?

For what value of k are the points (k,2-2k)(k+1,2k) and (-4-k,6-2k) are collinear?

For what value of k are the points (k,2-2k),(-k+1,2k) and (-4-k,6-2k) collinear?

Find the value of k for which the points A(k+1, 2k), B(3k, 2k +3) and C(5k-1, 5k) are collinear.

Find the values of k, if the points A (k+1,2k) ,B (3k,2k+3) and C (5k-1,5k) are collinear.

the value of k for which the points (3k-1,k-2),(k,k-7) and (k-1,-k-2) are collinear.

If the points (5, 2, 4), (6, -1, 2) and (8, -7, k) are collinear, then k =

(i) If the points (1,4),(3,-2)and (k,1)B(3k,2k+3)andC(5k-1,5k) are collinear, fine the value of k. (ii) If the points A(k+1,2k),B(3k,2k+3),B(3k,2k+3)andC(5k-1,5k) are collinear, then show that x + y =2.
