    Linear Transformation R2->R3 with 'zero' vector

    Homework Statement Is T(X,Y)->(X,Y,1) a linear transformation? where X and Y are defined R2 column vectors. Homework Equations Attempt to prove T(cX+Y)=cT(X)+T(Y) Consider T(cx1+y1,cx2+y2)->(cx1+y1,cx2+y2,1) The Attempt at a Solution RS=cT(x1,y1)+T(x2,y2)->c(x1,y1,1)+(x2,y2,1)...
