(8,4)and(9,-9)
trying to find slope m=
==============
slope = (change in y)/(corresponding change in x)
----------------
m = (-9-4)/?
Notice the order in which the y-values were selected.
You MUST use the same order in selecting the x-values
m = (-9-4)/(9-8)
m = -13/1
m = -13
==============
Cheers,
