Answer 1

line segment eq= y +2= 9( x-2)
= y+2 = 9x -18
y-9x +20=0

intersection point with 2x + y - 4 = x =24/11

y = 216/11 - 20

= -4/11

now ( 24/11) divide the line segment u can find
by
equating in

x = (mx2 + nx1)/m+n

y= (my2+ ny1)/m+n

u will get two equation in m and n

to have values of m and n that is ratio
