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


m=%288-4%29%2F%282-0%29 Plug in y%5B2%5D=8, y%5B1%5D=4, x%5B2%5D=2, and x%5B1%5D=0


m=%284%29%2F%282-0%29 Subtract 4 from 8 to get 4


m=%284%29%2F%282%29 Subtract 0 from 2 to get 2


m=2 Reduce


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