Question

Write the equation of a line that passes through the point (2, – 3).

Also write the equation of a line which coincides with this line.​

Answer 1

Answer:

The line parallel to x-axis and passing through the origin is x-axis itself.

Let A be a point on x-axis. 

Therefore, the coordinates of A are given by (a,0,0), where a∈R.

Direction ratios of OA are (a−0)=a,0,0.

The equation of OA is given by,

ax−0=0y−0=0z−0

1x=0y=0z=a

Thus, the equation of line parallel to x-axis and passing through origin is 

1x=0y=0z
