If the sum of the reciprocals of the intercepts made by a line on the coordinate axes is 7 ,then the line always passes through

. If the sum of the reciprocals of the intercepts made by the plane ax +by+cz=1 on the three axes is 1 then the plane always passes through the point:

A variable plane moves so that the sum of the reciprocals of its intercepts on the coordinate axes is (1//2) . Then, the plane passes through the point

A variable plane moves in such a way that the sum of the reciprocals of its intercepts on the three coordinate axes is constant.Show that the plane passes through a fixed point.

A straight line moves so that the sum of the reciprocals of its intercepts on two perpendicular lines is constant then the line passes through-

Astraight line moves so that the sum of the reciprocals of its intercepts made on axes is constant. Show that the line passes through a fixed point.

Find the intercepts made by the line 3x - 2y - 6 = 0 on the coordinate axes .

If the centroid of the triangle ABC is at the origin and algebraic sum of the lengths of the perpendiculars from the vertices of the triangle ABC on the variable line L is equal to 1 then sum of the squares of the reciprocals of the intercepts made by L on the coordinate axes is equal to
