Draw the straight line parallel to the compounded initial line #theta= 0 and theta = pi#, at a distance 3. in the direction #theta = 3/2pi#.

Explanation:

This is the polar form for# y = -3#

Here, #r = 3sec(theta+ 90^o)=3(-csc theta)=-3/sin theta#

So, y = r sin theta = -3

Draw the straight line parallel to the compounded initial line #theta= 0 and theta = pi#, at a distance 3. in the

direction #theta = 3/2pi#.
