Answer:
if (-4,-1),(-2,1) and (k,3) are colinear
than |-4 -1 1 -2 -1 1 k 3 1| =0
-4(1-3)-(-1)(-2-k)+1(-6-k)=0
-4(-2)+1(-2-k)+(-6-k)=0
-8-2-k-6-k=0
-2k-16=0
-2k=16
k=16/-2
k=-8

Answer:
if (-4,-1),(-2,1) and (k,3) are colinear
than
l-4 -11 -2 -11 k 3 11 =0
→-4(1-3)-(-1)(-2-k)+1(-6-k)=0
→-4(-2)+1(-2-k)+(-6-k)=0
→-8-2-k-6-k=0
→-2k-16=0
→-2k=16
→k=16/-2
→k=-8
