Questions
Equation of line passing through and parallel to the line having direction cosines is
a
x−321=y−0−1=z−120
b
x−13=y+10=z1
c
2x3=y0=2z1
d
x+y−3=y−12=z−31
detailed solution
Correct option is B
The equation of the line passing through the point x1,y1,z1and parallel to the line whose direction ratios area,b,c isx−x1a=y−y1b=z−z1cHere the direction cosines are 32,0,12 , it implies that the direction ratios are3,0,1Therefore, the equation of the line passing through the point 1,−1,0and having direction ratios 3,0,1 is x−13=y+10=z1Talk to our academic expert!
