The equation of the given line is

This equation can be reduced as

⇒

On dividing both sides , we obtain,

…………….(1)

On comparing equation (1) with xcosƟ + ysinƟ = p, we get,

cosƟ = and sinƟ = and p = 1

Since, the value of sinƟ and cosƟ are negative,

Therefore, the respective values of Ɵ and p are and 1.
