+%28+y+-+%28-1%29+%29+%2F+%28+x+-+2+%29+=+%28+3+-%28-1%29%29+%2F+%28+-2+-+2+%29+
+%28+y+%2B+1+%29+%2F+%28+x+-+2+%29+=+%28+3+%2B+1%29+%2F+%28+-4+%29+
+%28+y+%2B+1+%29+%2F+%28+x+-+2+%29+=+4+%2F+%28+-4+%29+
+%28+y+%2B+1+%29+%2F+%28+x+-+2+%29+=+-1+
+y+%2B+1+=+-x+%2B+2+
+y+=+-x+%2B+1+
check answer:
(-2,3)
+y+=+-x+%2B+1+
+3+=+-%28-2%29+%2B+1+
+3+=+2+%2B+1+
+3+=+3+
and
(2,-1)
+-1+=+-2+%2B+1+
+-1+=+-1+
OK
