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


m=%28-5--5%29%2F%282--1%29 Plug in y%5B2%5D=-5, y%5B1%5D=-5, x%5B2%5D=2, and x%5B1%5D=-1


m=%280%29%2F%282--1%29 Subtract -5 from -5 to get 0


m=%280%29%2F%283%29 Subtract -1 from 2 to get 3


m=0 Reduce


So the slope of the line that goes through the points and is m=0
