Bài 3:
\(a,\dfrac{2}{-7}=\dfrac{2.\left(-11\right)}{\left(-7\right).\left(-11\right)}=\dfrac{-22}{77}\)
\(\dfrac{-3}{11}=\dfrac{-3.7}{11.7}=\dfrac{-21}{77}\)
Vì \(\dfrac{-22}{77}< \dfrac{-21}{77}\) nên \(\dfrac{2}{-7}< \dfrac{-3}{11}\)
\(b,\dfrac{2}{5}=\dfrac{2.13}{5.13}=\dfrac{26}{65}\)
\(\dfrac{6}{13}=\dfrac{6.5}{13.5}=\dfrac{30}{65}\)
Vì \(\dfrac{26}{65}< \dfrac{30}{65}\) nên \(\dfrac{2}{5}< \dfrac{6}{13}\)

- You → Me (Vì đây là câu trần thuật)
b: Tọa độ giao điểm là:
