XOZ-plane divides the join of (2,3,1) and (6,7,1) in the ratio a. 3:7                  b.  2:7        c. -3:7           d. -2:7

Explanation

Let` A = (2, 3, 1) and B = (6, 7, 1)`


Let the line joining A and B be divided by the `xz`-plane at point P in the ratio
`λ:1.`


Then, we have,


`P=((6lambda+2)/(lambda+1), (7lambda+3)/(lambda+1), (lambda+1)/(lambda+1))`
