You can put this solution on YOUR website!
Note: is the first point . So this means that x%5B1%5D=7 and y%5B1%5D=6.
Also, is the second point . So this means that x%5B2%5D=10 and y%5B2%5D=-9.


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


m=%28-9-6%29%2F%2810-7%29 Plug in y%5B2%5D=-9, y%5B1%5D=6, x%5B2%5D=10, and x%5B1%5D=7


m=%28-15%29%2F%2810-7%29 Subtract 6 from -9 to get -15


m=%28-15%29%2F%283%29 Subtract 7 from 10 to get 3


m=-5 Reduce


So the slope of the line that goes through the points and is m=-5
