P is ((m₁x₂+m₂x₁)/(m₁+m₂),(m₁y₂+m₂y₁)/(m₁+m₂))
where m₁:m₂=2:3, A(-2,6), B(3,-4)
P((2*3-2*3)/5, (18-8)/5)=(0,2)
gradient or slope=3/2
let equation be y=mx+c
m=3/2
c=y-mx=2-0*3/2=2
hence y=3x/2+2
or 3x-2y+4=0
where m₁:m₂=2:3, A(-2,6), B(3,-4)
P((2*3-2*3)/5, (18-8)/5)=(0,2)
gradient or slope=3/2
let equation be y=mx+c
m=3/2
c=y-mx=2-0*3/2=2
hence y=3x/2+2
or 3x-2y+4=0
