consider two points `A= (1,2)` and `B=(3,-1)`. Let `M `be a point on the straight line L: x + y =0.If `M `be a point on the line `L = 0` such that `AM+BM` is minimum, then the reflection of `M` in the line `x=y`is-

Consider two points A=(1,2) and B=(3,-1). Let M be a point on the straight line L=x+y=0 If M be a point on the line L=0 such that |AM-BM| is maximum,then the distance of M from N=(1,1) is

Consider the points A=(1,2) and B=(3,-1) .Let M be a point on x+y=0 such that |AM-BM| is minimum.If S denotes area of triangle AMB then (8S)/(13) is.
