Note: is the first point . So this means that x%5B1%5D=-4 and y%5B1%5D=-3.
Also, is the second point . So this means that x%5B2%5D=7 and y%5B2%5D=-9.


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


m=%28-9--3%29%2F%287--4%29 Plug in y%5B2%5D=-9, y%5B1%5D=-3, x%5B2%5D=7, and x%5B1%5D=-4


m=%28-6%29%2F%287--4%29 Subtract -3 from -9 to get -6


m=%28-6%29%2F%2811%29 Subtract -4 from 7 to get 11


So the slope of the line that goes through the points and is m=-6%2F11
