Just plot the points on a graph.
Use these equations when converting polar equations to parametric equations:
We know that 
, so substitute that into both equations for x and y.
Now, replace 
with any variable that you want to represent the parametric equations in. I'll use the standard variable, 
Thus, represented in parametric form is:
Let me know if you need any clarifications, thanks!
