    do you know the rule of parallelism?

    Two vectors and are parallel if their cross product is zero, i.e., .u*v=0

    one of them may probable be y=-1/2x+2z

    when two equations are parallel they have the same slopes

    as it says parallel the equation is linear so it's form is y=kx+b , but here instead of k it will be the slope

    then as vectors usually start at (0,0) point

    you can substitue it into the formula \[Y_{1}-Y _{2}=m(X _{1}-X _{2})\]

    given this equation: x=4y+2z=16.
