Gọi pt đường thẳng có dạng \(y=ax+b\)
\(\Rightarrow\left\{{}\begin{matrix}\sqrt{2}a+b=4-\sqrt{2}\\2a+b=\sqrt{2}\end{matrix}\right.\)
\(\Rightarrow\left\{{}\begin{matrix}\left(2-\sqrt{2}\right)a=2\sqrt{2}-4\\2a+b=\sqrt{2}\end{matrix}\right.\)
\(\Rightarrow\left\{{}\begin{matrix}a=-2\\b=4+\sqrt{2}\end{matrix}\right.\)
