Questions
The equation of a line passing through the point on axis at a distance of 3 units from the origin and parallel to plane is
a
x−31=y−21=z3
b
x−31=y−01=z−00
c
x3=y1=z1
d
x3=y0=z0
detailed solution
Correct option is B
The direction cosines of any line parallel to the xy-plane is 1,1,0and the coordinates of the point which are on x-axis and at a distance of 3 units from the origin is 3,0,0Therefore, the equation of the line passing through the point 3,0,0and parallel to the line whose direction ratio are1,1,0 is x−31=y−01=z−00Talk to our academic expert!
