The point collinear with (1,−2,−3) and (2,0,0) among the following is
Open in App
Solution
The correct option is B (0,−4,−6)
Any point lying on the line joining (1,−2,−3) and (2,0,0) can be written in the form of (1+k,−2+2k,−3+3k).
Since, all the options have their x coordinate as 0,
1+k=0
k=−1
Thus, y=−2+2k=−4 and z=−3+3k=−6Hence, option C is correct.
