Question

find the equation of line through origin having inclination of
120°​

Answer 1

Step-by-step explanation:

Equation of line passing through origin is

y = mx

where m is slope of straight line

Given that the line makes an inclination of 120°

Hence, slope of straight line is tan120° = - root(3)

Equation of line is

$y = ( - \sqrt{3} )x \\ \sqrt{3} x + y = 0$

Answer 2

Step-by-step explanation:

Equation of line passing through origin is

y = mx

where m is slope of straight line

Given that the line makes an inclination of 120°

Hence, slope of straight line is tan120° = - root(3)

Equation of line is

\begin{gathered}y = ( - \sqrt{3} )x \\ \sqrt{3} x + y = 0\end{gathered}

y=(−
