The point P = (-3, 1, -1) is on a line, L, that is parallel to v = . Determine another point on L.

Question

The point P = (-3, 1, -1) is on a line, L, that is parallel to v = <2,4,-3>. Determine another point on L.

just add 2 toghter

anonymous · Answer

L is parallel to V if its direction vector is equal?

amistre64 · Answer

teh vector points to a position as well as a direction; so if you add it to the point; or even subtract it; or any scalar of it; you get a new point on the line

amistre64 · Answer

By L and v being parallel; v is the vector for the line

amistre64 · Answer

vector arent stationary, they move; just attach it to the point and count

amistre64 · Answer

(-3, 1, -1)
 <2,4,-3>
---------
-1,5,-4  is a point on the line

amistre64 · Answer

in fact the line is comprised as:

x=-3+2t
y=  1+4t
z=-1-3t

anonymous · Answer

Ah yea ok, since vectors are parallel if they have a scalar multiple.

yep :)
