Correct Answer: Option A

Explanation

The line x + y + 4 = 0

y = - x - 4 (in the slope-intercept form)

m = -1

But, Tan \(\theta\) = - 1 = slope/gradient

\(\theta\) = tan\(^{-1}\)(-1) = - 45º

But, tan -45º is in the fourth quadrant, since the line made an angle with the x-axis, the positive value = 360 - 45 = 315\(^0\)
