Find the equation of the line passing through (0,0) with slope `mdot`

Explanation

We know that, the equation of line passing through point `(x_o,y_o)` whose slope is m is

`(y-y_o) = m (x-x_o)`


Thus the equation of the line passing through the point (0,0) with slope m is `(y-0) = m(x-0) `


` y=mx`
