The answer is the function is not one to one
Let
be the line given by the vector equation
.
First, we use the director vectors of the lines L1 and L2 to get the
vector equation of the plane containing them, which we denote by
. This is,

We observe that
. Therefore, the vector equation of
defines a plane and
is a normal vector to 
Finally, the vector equation for the wanted plane, which we denote by
, is
Thus, if
, then
and since
is parallel to
, then it is perpendicular to
.
Answer:
m= 1/3
Step-by-step explanation:
to find slope: y2-y1/ x2-x1 so,
3-2/4-1= 1/3
