The line $y = 2 - x$ intersects the graphs of the two logarithmic functions $y = \log _ { 2 } x , y = \log _ { 3 } x$ at points $\left( x _ { 1 } , y _ { 1 } \right), \left( x _ { 2 } , y _ { 2 } \right)$ respectively. Which of the following in are correct? [4 points]
ㄱ. $x _ { 1 } > y _ { 2 }$ ㄴ. $x _ { 2 } - x _ { 1 } = y _ { 1 } - y _ { 2 }$ ㄷ. $x _ { 1 } y _ { 1 } > x _ { 2 } y _ { 2 }$
