You can put this solution on YOUR website! Convert the equation to rectangular form.
---------------------
r = sqrt(x^2+y^2)
theta = arctan(y/x)
-------
If tan(t) = y/x, csc(t) = sqrt(x^2+y^2)/y
============================
Substitute to get an equation in x and y.
-----------------------
sqrt(x^2+y^2) = -6[sqrt(x^2+y^2)/y
----
y = -6
