Question

find the equation of y-axis ​

Answer 1

Answer:

The equation of y-axis is x = 0, since, y-axis is a parallel to itself at a distance 0 from it. 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.

Answer 2

$x= 0 \\ \: \: \: \: \: \: \: \: \: \: \: is \: the \: equation \: of \: y \: axis.$
