A(3,4)  B(4,13)
consider a point on the line Y=X,  p(a,a)
PA+PB=
1 5 1
thanks for your answer but I am not satisfied
get me the coordinates of p
when you have PA+PB=M (let)
then find dM/da,for mini value of M dM/da=0

Let the coordinates of p be (a,a) ( as x=y)
as the distance is same so, PA=PB
now find PA+PB
0
