basically how to find a plane parallel to a given line??

- maths --plse help me.. -
**Reiny**, Friday, December 28, 2012 at 5:15pmWe need two direction vectors in the plane, one is vector AB or (3, -1, 2)

the other is the direction of the line parallel to the plane which is ((1, -4, 7)

a normal to the plane would be the cross - product of the two vectors above

Assuming you know how to find that normal, I got

(1 , -19, -11)

So the plane has equation,

x - 19y - 11z = c

but (0,0,0) lies on it,

so

x - 19y -11z = 0
