Question

Find the equation of the line which passes through (0,0) with slope m.

Answer 1

We know that 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 point (0,0), whose slope is m is,

$(y-0)=m(x-0)$

$y=mx$
