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


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


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


m=%288%29%2F%282--2%29 Subtract -4 from 4 to get 8


m=%288%29%2F%284%29 Subtract -2 from 2 to get 4


m=2 Reduce


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