Question

determine the ratio in which the line 3 X + Y - 9 = 0 divides the line segment joining the points 1, 3 and 2, 7

Answer 1

let the ratio be k:1
x=mx2+nx1 upon m+n
Y= my2+ny1 upon m+n
so
the value of x and Y will come then putting the value of x and Y in equation 3x + Y -9 =0
then
the ratio is (x,y) is come
