Answer 7

sorry, no time right now .. but
2x + 2y + 3z = -1, substituting in your (1, -3, 1)
2*(1) + 2*(-3) +3*(1) = -1
2 -6 +3 = -1 , true

4x + 4y + 3z = -5
4*(1) + 4*(-3) + 3*(1) = -5
4 -12 +3 = -5, true ,,

4x +2y + 2z =0
4*(1) +2*(-3) +2*(1) = 0
4 -6 +2 = 0, true

so, yes, just can't go thru the proof just now
you are correct
