I am suppose to graph it in the rectangular coordinate system.  I understand the answer is 0 but what I am wondering is can I actually draw a triangle?  Wouldn't it just be a point at (0,-1)?  My teacher is looking for reference triangles but I don't know how I could draw one with this point.  Thanks. </SPAN>\n" );
