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 3

*x + 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 3

*x + y*– 9 = 0 divides the segment joining A (1, 3) and B (2, 7) in the ratio 3:4.
