You can put this solution on YOUR website! find the slope, if it exists, of the line containing the pair of points:
(5,4) and (9,-10) =
---------------------------------
slope m = diffy/diffx
-----------
(5,+4)
(9,-10)
-------- Subtract
-4,14
Difference in y = 14
Difference in x = -4
m = 14/-4 = -7/2 = -3.5
