Answer :

Given : A line


To find : Direction cosines of the line parallel to


Formula used : If a line is given by = = then direction cosines are given by , ,


The line is = =


Parallel lines have same direction ratios and direction cosines


Here l = -2 , m = 2 , n = 1


Direction cosines of the line = = is


, ,


= , , = , ,


= , ,


Direction cosines of the line parallel to the line = = is


, ,
