​

Answer 1

Answer:

hey here is your solution

pls mark it as brainliest

Step-by-step explanation:

$so \: we \: know \: that \\ tan \: 120 = tan \: (\pi - \frac{\pi}{3} \: ) \\ \\ = tan \: \frac{\pi}{3} \\ \\ = tan \: 60 \\ \\ = \sqrt{ 3} \\ \\ but \: as \: 120 \: lies \: in \: quadrant \: 1 \\ tan \: 120 = - \sqrt{3} \\ \\ hence \: then \\ slope \: (m) = - \sqrt{3}$
