Note: is the first point . So this means that x%5B1%5D=2 and y%5B1%5D=5.
Also, is the second point . So this means that x%5B2%5D=-1 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=%281-5%29%2F%28-1-2%29 Plug in y%5B2%5D=1, y%5B1%5D=5, x%5B2%5D=-1, and x%5B1%5D=2


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


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


m=4%2F3 Reduce


So the slope of the line that goes through the points and is m=4%2F3
