If  x = 2
x2 - 2kx + 5 = 0
 (2)2 - 2k(2) + 5 = 0
4 - 4k + 5 = 0
-4k + 9 = 0
4k = 9
k = 9/4

X1=2 Y1=3 x=4 m1=k X2=6 Y2=-3 y=m m2=1 By applying section formula, (4,m)= k (6)+1 (2)/k+1, k(3)+1 (-3)/k+1 (4,m)= 6k+2/k+1, 3k-3/k+1 4=6k+2/k+1, m=3k-3/k+1 4 (k+1)=6k+2, m(k+1)=3k-3 4k+4=6k+2, mk+m =3k-3 6k-4k =2-4, m (-1)+ m=3 (-1)-3 2k=-2 , -m+3m = -3-3 K=-1 , 2m =-6 m=-3
