Find parametric equations of the line of intersection of the two planes

-8 x - 2 y + 3 z = 9

and

5 x + 4 y + 2 z = -8

. Assign your direction vector, as a Maple list, to the name DirectionVector.

================================================== ======

This is a repeat question that i cant figure out. If you take the crossproduct o both vectors, that returns you the normal vector which is apraeel correct? The answer i got is [-16,31,-22], but the computer keeps telling me that its not parallel to a correct direction vector for the line. Happy labor day everyone.
