Note: is the first point . So this means that x%5B1%5D=2 and y%5B1%5D=3.
Also, is the second point . So this means that x%5B2%5D=4 and y%5B2%5D=1.


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


m=%281-3%29%2F%284-2%29 Plug in y%5B2%5D=1, y%5B1%5D=3, x%5B2%5D=4, and x%5B1%5D=2


m=%28-2%29%2F%284-2%29 Subtract 3 from 1 to get -2


m=%28-2%29%2F%282%29 Subtract 2 from 4 to get 2


m=-1 Reduce


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