Q8 of 136 Page 28

Write the coordinate axis to which the line is perpendicular.

We have,



The given line is parallel to the vector,



Now let,


be perpendicular to the given line.


Now,


3x+4y+0z = 0


It is satisfied by the coordinates of z-axis, i.e. (0,0,1).


Hence, the given line is perpendicular to z-axis.
