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.

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.

A straight 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.

A variable plane moves so that the sum of reciprocals of its intercepts on the three coordinate axes is constant lambda . It passes through a fixed point whose coordinate are (a) (lambda,lambda,lambda) (b) ((-1)/lambda,(-1)/lambda,(-1)/lambda) (c) (1/lambda,1/lambda,1/lambda) (d) (-lambda,-lambda,-lambda)dot

If 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
