    The original is the special name for the point (0,0). It acts like any other ordered pair (a,b)

    hi
    well,when a line passes through the origin ( which is the couple (0,0) ) the y intercept will equal zero.and hence any line that passes through the origin will have the equation y=mx .

    Almost true. The line x= 0 passes through the origin but does not have that form.
