Erro no comando de reta

Not a Problem

O GeoGebra (online e app) não estão entendendo o comando "reta(<ponto>,<vetor diretor>)", estão achando que é "reta(<ponto>,<ponto>)".

If you type just coordinates, GG will always regard them as a point no matter which syntax option you select. The options just indicate what's possible, and don't determine that coordinates are points whether vectors. So if you define u = (2,1,3) and Line( (1,1,1), u) GeoGebra knows the first parameter is a point, the second parameter is a vector and will create the line you wanted.

Of course you can also define Line((1,1,1), Vector((0,0,0), (2,1,3))) to get the same result.
