The formula for the slope of a straight line passing through two given points    (x%5B1%5D,y%5B1%5D)    and    (x%5B2%5D,y%5B2%5D)    is

m = %28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29.



Substitute the given data into this formula and calculate


m = %28-2-12%29%2F%28-6-6%29 = %28-14%29%2F%28-12%29 = 7%2F6.


Answer.  The slope is 7%2F6.
