+%28+x%5BK%5D+%2B+x%5BL%5D+%29+%2F+2+=+-8+
+x%5BK%5D+=+-6+, so
+%28+-6+%2B+x%5BL%5D+%29+%2F+2+=+-8+
+-6+%2B+x%5BL%5D+=+-16+
+x%5BL%5D+=+-10+
--------------
+%28+y%5BK%5D+%2B+y%5BL%5D+%29+%2F+2+=+1+
+y%5BK%5D+=+5+
+%28+5+%2B+y%5BL%5D+%29+%2F+2+=+1+
+5+%2B+y%5BL%5D+=+2+
+y%5BL%5D+=+-3+
The coordinates of endpoint L are L(-10, -3)
