Question

a line makes 120° with x-axis, then its slope is

Answer 1

Answer: m = -1/$\sqrt3$

Step-by-step explanation:

m = tan theta

m = tan 120

m = -1/$\sqrt 3$

Answer 2

Answer:

slope is

$m = -1/\sqrt3$

Step-by-step explanation:

$m = tanθ$

$here \: θ = 120$

$= \tan(120) = \tan(180 - 60) = - \tan(60) = - \frac{1}{ \sqrt{3} }$

Hence the slope is

$m = -1/\sqrt3$
