Note: is the first point . So this means that x%5B1%5D=-6 and y%5B1%5D=-10.
Also, is the second point . So this means that x%5B2%5D=-15 and y%5B2%5D=-11.


m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29 Start with the slope formula.


m=%28-11--10%29%2F%28-15--6%29 Plug in y%5B2%5D=-11, y%5B1%5D=-10, x%5B2%5D=-15, and x%5B1%5D=-6


m=%28-1%29%2F%28-15--6%29 Subtract -10 from -11 to get -1


m=%28-1%29%2F%28-9%29 Subtract -6 from -15 to get -9


m=1%2F9 Reduce


So the slope of the line that goes through the points and is m=1%2F9
