id say -6
OpenStudy (anonymous):
thx
OpenStudy (amistre64):
in order to have no solution; the lines have to be parallel and NOT scalars of each other. the 19 takes care of the second caveat
OpenStudy (amistre64):
so if we simply scale the rest of it we are good to go
OpenStudy (amistre64):
4(2) = 8 -3(2) = -6
