You can put this solution on YOUR website!
slope is [ change in y ] / [ change in x ]
( w,10 ) , ( -6,-10 )
+10+=+%28+10+-%28-10+%29+%29+%2F+%28+w+-%28+-6+%29+%29+
+10+=+%28+10+%2B+10+%29+%2F+%28+w+%2B+6+%29+
+10+=+20+%2F+%28+w+%2B+6+%29+
+10%2A%28+w+%2B+6+%29+=+20+
+w+%2B+6+=+2+
+w+=+-4+
---------------------
check:
+10+=+20+%2F+%28+w+%2B+6+%29+
+1+=+2+%2F+%28+-4+%2B+6+%29+
+1+=+2+%2F+2+
+1+=+1+
OK
