The slope is #3#

Explanation:

We can easily prove it by seen that when #x# changes its value from #5# to #7#, #y# changes it from #-3# to #3#.

So, when #x# rises #2#, #y# rises ##6.

So, when #x# rises by #1#, #y# rises by #3#,

#(y-rise[6]) / (x-rise[2]#

simplified as

#(y-rise[3]) / (x-rise[1])#
