Question

Find the equation of line passing through the point
(-1,2) and parallel to X-axis​

Answer 1

Step-by-step explanation:

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,
