Find the Slope

What is the slope of the line that goes through the two points (-5 , 11) & (12 , 3)?

---

change in y
----------------- = slope of the line
change in x

(-5,11) and (12,3)

3 - 11
----------- = slope {subtracted the y-coordinates over subtracting the x-coordinates}
12 - (-5)

-8
-----  = slope  {subtracted in numerator and denominator}
17

slope = -8/17
