Given -
m1 : m2
,____________,______________,
A(2,-3) P(x,y) B(3,9)
x= 3(m1) + 2(m2) y= 9(m1) + (-3)(m2)
___________ , _____________ [by section formula]
m1 + m2 m1 + m2
P = 2x + y =5
P = 2 {3(m1)+2(m2) + {9(m1) + (-3)(m2) - 5 = 0
___________ _____________
m1 + m2 } m1 + m2
= 6m1 + 4m2 + 9m1 - 3m2 - 5m1 - 5m2 = 0
= 10m1 - 4m2 = 0
= 10m1 =4m2
= m1/m2 = 4/10
= m1/m2 = 2/5
m1:m2 = 2:5
