The given slope is .
Take note that if the slope of the line is given, to determine the angle of inclination, apply the formula:
where is the angle measured counterclockwise from the positive x-axis going to the right of the line. And its range of values is from 0 to 180 degree only
.
Plugging in the value of m, the formula becomes:
Then, take the inverse of tangent to isolate theta.
Take note that when the computed value is negative, to get value of angle of inclination in the interval , add 180 degree (pi rad).
rad
Therefore, in radians, the angle of inclination is rad. And in degree, the angle of inclination is
.
