Hi Aditya,
Thanks for the alternative method, which comes handy if one wishes to extend the straight line by a different amount at either end:
\starttext
\startMPcode
z1 = (1cm,3cm) ;
z2 = (5cm, 9cm) ;
z3 = 1cm * dir(angle (z2 - z1)) shifted z2 ;
z4 = -.5cm*dir(angle(z2 - z1)) shifted z1 ;
draw z1 -- z3 ;
draw z4 -- z1 ;
draw z1 -- z2 withcolor red ;
\stopMPcode
\stoptext
Best regards: Otared
