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 y – 2 = 0
0 × x + 1 × y = 2
Dividing both sides by
The above equation is of the form x cos θ + y sin θ = p, where θ = 90° and p = 2.
Perpendicular distance of line from origin = 2
Angle between perpendicular and positive x – axis = 90°
