Tọa độ A là:
\(\left\{{}\begin{matrix}2x-2=\dfrac{1}{3}x+3\\y=2x-2\end{matrix}\right.\)
=>\(\left\{{}\begin{matrix}\dfrac{5}{3}x=5\\y=2x-2\end{matrix}\right.\Leftrightarrow\left\{{}\begin{matrix}x=5:\dfrac{5}{3}=3\\y=2\cdot3-2=6-2=4\end{matrix}\right.\)
Vậy: A(3;4)
Tọa độ B là:
\(\left\{{}\begin{matrix}-\dfrac{4}{3}x-2=\dfrac{1}{3}x+3\\y=\dfrac{1}{3}x+3\end{matrix}\right.\)
=>\(\left\{{}\begin{matrix}-\dfrac{5}{3}x=5\\y=\dfrac{1}{3}x+3\end{matrix}\right.\Leftrightarrow\left\{{}\begin{matrix}x=-3\\y=\dfrac{1}{3}\cdot\left(-3\right)+3=3-1=2\end{matrix}\right.\)
Vậy: B(-3;2)
