Note: is the first point . So this means that x%5B1%5D=19 and y%5B1%5D=-16.
Also, is the second point . So this means that x%5B2%5D=-7 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--16%29%2F%28-7-19%29 Plug in y%5B2%5D=-15, y%5B1%5D=-16, x%5B2%5D=-7, and x%5B1%5D=19


m=%281%29%2F%28-7-19%29 Subtract -16 from -15 to get 1


m=%281%29%2F%28-26%29 Subtract 19 from -7 to get -26


m=-1%2F26 Reduce


So the slope of the line that goes through the points and is m=-1%2F26
