Note: is the first point . So this means that x%5B1%5D=9 and y%5B1%5D=3.
Also, is the second point . So this means that x%5B2%5D=4 and y%5B2%5D=2.


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


m=%282-3%29%2F%284-9%29 Plug in y%5B2%5D=2, y%5B1%5D=3, x%5B2%5D=4, and x%5B1%5D=9


m=%28-1%29%2F%284-9%29 Subtract 3 from 2 to get -1


m=%28-1%29%2F%28-5%29 Subtract 9 from 4 to get -5


m=1%2F5 Reduce


So the slope of the line that goes through the points and is m=1%2F5
