Slope = [ change in y ] / [ change in x ]
( 6,-19 ), ( x, -25 ), and slope = +-3+
-----------------------------------------
+%28+-19+-%28-25%29+%29+%2F+%28+6+-+x+%29+=+-3+
+%28+-19+%2B+25+%29+%2F+%28+6+-+x+%29+=+-3+
+6+=+-3%2A%28+6+-+x+%29+
+6+=+-18+%2B+3x+
+3x+=+24+
+x+=+8+
--------------------
check:
+%28+-19+%2B+25+%29+%2F+%28+6+-+8+%29+=+-3+
+6+%2F+%28-2%29+=+-3+
+6+=+%28-2%29%2A%28-3%29+
+6+=+6+
OK
