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 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 minum, 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 minimum, then the reflection of M in the line x = y 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.

Number of points having distance sqrt5 from the straight line x-2y+1=0 and a distance sqrt13 from the lines 2x+3y-1=0 is

A line passing a given point A(x_(1),y_(1),z_(1)) has direction cosines l,m,n If is a point on the line such that AP = r then the co ordinates of P are .

Let (2,-1) be the point P and x- y + 1 =0 be the straight line l. If Q is image of point P about line, that image of point Q about y-axis is

Find the distance of the point P from the line l in that : l: 12x-7=0 -= (3, -1)

If the straight line y=mx+1 be the tangent of the parabola y^(2)=4x at the point (1,2) then the value of m will be-
