Question

A plane passes through the point p(4,0,0) and q(0,0,4) and is parallel to the y axis .The distance of the plane from the origin is

Answer 1

`\displaystyle\\\text{The distance of the plane from the origin is:}\\\\d=(√(4^2+4^2))/(2)=(√(2*4^2))/(2)=(4√(2))/(2)=2√(2)\\\\\boxed{\bf d=2√(2)~cm}`
