Show that the line joining the origin to...

Show that the line joining the origin to the point `(2,1,1)` is perpendicular to the line determined by the points `(3,5,-1)` and `(4,3,-1)dot`

Text Solution

Verified by Experts

The correct Answer is:
`(x -1)/(2) = (y - 2)/(3) = (z + 4)/(6)` (ii) `(x -2)/(2) = (y - 1)/(-7) = (z - 3)/(4)`
