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
