Find the ratio in which the line 3x + y - 9 = 0 divides the line segment joining the points A(1,3) and B(2,7)

Let be line 3x + y – 9 = 0 divides the line segment joining the pints A (1, 3) and B (2, 7) in the ratio k: 1 at point C.
Thus, the line 3x + y – 9 = 0 divides the segment joining A (1, 3) and B (2, 7) in the ratio 3:4.

why is the ratio taken as k:1?
plzzz answer

suppose the line 3x+y-9=0 divides the line sebment joining A(1,3) and B(2,7) in the ratio k:1 at point C. then the coordinates of C are
{2k+1 7k+3}
   k+1      k+1
but, C lies on 3x+y-9=0. therefore
3{2k+1 }+ 7k+3    -9=0 => 6k+3+7k+3-9k-9=0 => k=3/4
     k+1         k+1
