$$Q1:$$$$3+2t+6t-t=-4\Rightarrow t=-1\Rightarrow p(1,-2,-1)$$$${\overrightarrow{u}}_L={\overrightarrow{n}}_P=(1,3,-1)\Rightarrow L^{\prime }:x=t+1\mathrm{\&}y=3t-2\mathrm{\&}z=-t-1$$$$Q2:$$$$AB(2,0,-1),AC(2,-1,0)$$$$\overrightarrow{N}=A\overrightarrow{B}\times A\overrightarrow{C}=(1,2,2)\Rightarrow P:x+2y+2z=0$$$$\Rightarrow PH=\frac{\mid 1+8\mid }{\sqrt{1+4+4}}=1✓$$$$Q3:$$$$itisnotclear$$
