Note: is the first point . So this means that x%5B1%5D=-2 and y%5B1%5D=7.
Also, is the second point . So this means that x%5B2%5D=-9 and y%5B2%5D=-4.


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


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


m=%28-11%29%2F%28-9--2%29 Subtract 7 from -4 to get -11


m=%28-11%29%2F%28-7%29 Subtract -2 from -9 to get -7


m=11%2F7 Reduce


So the slope of the line that goes through the points and is m=11%2F7
