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=-5 and y%5B2%5D=10.


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


m=%2810--2%29%2F%28-5-5%29 Plug in y%5B2%5D=10, y%5B1%5D=-2, x%5B2%5D=-5, and x%5B1%5D=5


m=%2812%29%2F%28-5-5%29 Subtract -2 from 10 to get 12


m=%2812%29%2F%28-10%29 Subtract 5 from -5 to get -10


m=-6%2F5 Reduce


So the slope of the line that goes through the points and is m=-6%2F5
