Answer:
Option A. -()
Step-by-step explanation:
Equation of a given line is a + 4b = 0 or b = -
This in the form of y = mx + b, which is slope-intercept form.
Here slope of the line is ().
Or tanθ =
This line coincides with the terminal side of the angle in standard position where cosθ > 0
Since tanθ =
and sinθ =
Hypotenuse =
=
=
Since tanθ is negative and cosθ > 0 that means θ lie in fourth quadrant.
Therefore, sinθ will be negative.
[ ]
sinθ = -
= -
Answer will be option A.
