y2 - y1
------- = slope
x2 - x1

(2,9) , (7,-2)

-2 - 9
------ = slope {substituted into slope formula}
7 - 2

-11
---- = slope {simplified on top and bottom}

find the slope if it exists, of the line containing the pair of points.
(2,9) and (7,-2)
--------------------
slope = (9--2)/(2-7) = 11/-5 = -11/5
