Yes, very nicely done!

Those of us who dislike fractions (third grade trauma!) might prefer

2x- y+ 2z= 0 for the tangent plane (multiply your equation by -2) and
[2t, 2- 2t, 1+ 2t] for the normal line (replace your t by -2t) but your equations are completely correct.
 P: 160 HoI, thank you very much!
