Let a complex number (z) = 1/1+i

now,
z = 1/2 -i/2
so real part of z = x = 1/2
Imaginary part of z = y = 1/2
∴

Argument = tan⁻¹(y/x)

Let {tex}\theta{/tex} be the angle of inclination of the given line with the positive direction of the x-axis in anticlockwise sense.
Then, its slope is given by m = tan {tex}\theta{/tex}.
If the slope of the line is negative, then
slope = m = tan {tex}\theta{/tex} < 0
{tex}\Rightarrow{/tex} {tex}\theta{/tex} lies between 90° and 180°
{tex}\Rightarrow{/tex} {tex}\theta{/tex} is an obtuse angle.
Therefore, a line of negative slope makes an obtuse angle with the positive direction of x-axis in anticlockwise direction.
