Question

Obtain the equation of the line which is parallel to the Y-axis and 2 units to the left of it.

Answer 1

Equation of a line parallel to Y-axis is x = h.
Since, the line is at a distance of 2 units to the left of Y-axis.
∴ h = – 2
∴ the equation of the required line is x = – 2 i.e., x + 2 = 0.
