Note: is the first point . So this means that x%5B1%5D=-8 and y%5B1%5D=14.
Also, is the second point . So this means that x%5B2%5D=2 and y%5B2%5D=-11.


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


m=%28-11-14%29%2F%282--8%29 Plug in y%5B2%5D=-11, y%5B1%5D=14, x%5B2%5D=2, and x%5B1%5D=-8


m=%28-25%29%2F%282--8%29 Subtract 14 from -11 to get -25


m=%28-25%29%2F%2810%29 Subtract -8 from 2 to get 10


m=-5%2F2 Reduce


So the slope of the line that goes through the points and is m=-5%2F2
