Note: is the first point . So this means that x%5B1%5D=5 and y%5B1%5D=2.
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=%28-1-2%29%2F%284-5%29 Plug in y%5B2%5D=-1, y%5B1%5D=2, x%5B2%5D=4, and x%5B1%5D=5


m=%28-3%29%2F%284-5%29 Subtract 2 from -1 to get -3


m=%28-3%29%2F%28-1%29 Subtract 5 from 4 to get -1


m=3 Reduce


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