Reduce the

Answer :

Equation of line in normal form is given by x cos θ + y sin θ = p where ‘θ’ is the angle between perpendicular and positive x axis and ‘p’ is perpendicular distance from origin.


Given equation is x – y + 8 = 0



Dividing both sides by





The above equation is of the form x cos θ + y sin θ = p, where θ = 120° and p = 4.


Perpendicular distance of line from origin = 4


Angle between perpendicular and positive x – axis = 120°
