Q2 of 319 Page 24

Reduce the following equations to the normal form and find p and α in each case :

Given:


Explanation:




Dividing both sides by



Hence, the normal form of the given line, where p = 2, cosα = and sin α =


⇒ α = 135


The coefficient of x and y are negative and positive respectively. So, α lies in the second quadrant
