Dear Zamil,


 


Take A as ( a, 0) - x axis and B as (0, b ) y axis i.e A is on floor and B is on wall.


Eq of a line from A and B is x/a + y/b = 1


let point x1, y1 divide this line in 2:3 then


x1 = 0+3a/5 and y1 = 2b/5


put value of a , b from above in x/a + y/b = 1


so locus is ---          3x/x1 + 2y/y1 = 5
