Note: is the first point . So this means that x%5B1%5D=-2 and y%5B1%5D=-1.
Also, is the second point . So this means that x%5B2%5D=6 and y%5B2%5D=3.


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


m=%283--1%29%2F%286--2%29 Plug in y%5B2%5D=3, y%5B1%5D=-1, x%5B2%5D=6, and x%5B1%5D=-2


m=%284%29%2F%286--2%29 Subtract -1 from 3 to get 4


m=%284%29%2F%288%29 Subtract -2 from 6 to get 8


m=1%2F2 Reduce


So the slope of the line that goes through the points and is m=1%2F2
