Note: is the first point . So this means that x%5B1%5D=17 and y%5B1%5D=-12.
Also, is the second point . So this means that x%5B2%5D=-9 and y%5B2%5D=-15.


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


m=%28-15--12%29%2F%28-9-17%29 Plug in y%5B2%5D=-15, y%5B1%5D=-12, x%5B2%5D=-9, and x%5B1%5D=17


m=%28-3%29%2F%28-9-17%29 Subtract -12 from -15 to get -3


m=%28-3%29%2F%28-26%29 Subtract 17 from -9 to get -26


m=3%2F26 Reduce


So the slope of the line that goes through the points and is m=3%2F26
