 (L)សមីការបន្ទាត់(L)ដែលកាត់តាម​  
 M(1,2,3)ចំណុចM(-1,2,3)  
 U(2,1,2) ហើយមានវ៉ិចទ័រប្រាប់ទិស\overrightarrow{U}\left(2,1,2\right)\    

 មានសមីការកំណត់ដោយ៖  

 (L):x+12=y21=z\left(L\right):\frac{x+1}{2}=\frac{y-2}{1}=z  

 (L):x12=y+21=z1\left(L\right):\frac{x-1}{2}=\frac{y+2}{1}=\frac{z}{1}  

 (L):x+11=y+22=z1\left(L\right):\frac{x+1}{1}=\frac{y+2}{2}=\frac{z}{1}  

 (L):x12=y+21=z11\left(L\right):\frac{x-1}{2}=\frac{y+2}{1}=\frac{z-1}{1}
