Question

what is the linear equation for X axis


​

Answer 1

Answer:

y axis is very simple and easy to understand. X axis is a linear line so first we write equation of a line which is, $y = mx + b$. where $m$ = slope or tan of the angle which it makes with X axis and b is Y intercept or the point where the line cuts the $Y$ axis.

Answer 2

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