The geometric interpretation of a set

  1. Jan 28, 2017 #1
    1. The problem statement, all variables and given/known data
    Show the geometric interpretation of S is a plane in ##R^3## and find its equation
    ##S=\left\{ (a+b,2b,-a)\in { R }^{ 3 }|a,b\in R \right\} ##

    2. Relevant equations

    3. The attempt at a solution
    I know that S is the set of all points that lie in a plane, but have no idea where to go from there
