Try to find slope of the line, as the points are collinear
(1+2)/(5-7)=(2k-1)/(3-5)
-3/2=-(2k-1)/2
2k=4
k= 2
(1+2)/(5-7)=(2k-1)/(3-5)
-3/2=-(2k-1)/2
2k=4
k= 2

the answer according to me is
Try to find slope of the line, as the points are collinear
(1+2)/(5-7)=(2k-1)/(3-1)
-3/2=(2k-1)/2
-3=2k-1
2k=-3+1
2k=-2
k= -1
