Question

. Determine the ratio in which the line 3x + y - 9 – 0 divides the segment joining the points (1, 3)
and( 12, 7)​

Answer 1

Answer:

Let the line divides the points in k:1 ratio according to section formula

(2k+1/k+1, 7k+3/k+1) = (x, y)

It must satisfy the given equation so

3(2k+1/k+1) + (7k+3/k+1) = 9

6k+3+7k+3/k+1 = 9

13k+6=9k+9

13k-9k=9-6

4k=3

k=3/4
