Question

equation of a line parallel to y axis is​

Answer 1

hi..

Let P (x, y) be any point on the y-axis. Then clearly, for all position of P we shall the same abscissa 0 or, x = 0. Therefore, the equation of y-axis is x = 0. If a straight line is parallel and to the left of x-axis at adistance a, then its equation is x = -a.

Answer 2

equation of line parallel to y- axis is x=k
