I'll do the first one to get you started

# 1


Note: is the first point . So this means that x%5B1%5D=6 and y%5B1%5D=-2.
Also, is the second point . So this means that x%5B2%5D=1 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--2%29%2F%281-6%29 Plug in y%5B2%5D=3, y%5B1%5D=-2, x%5B2%5D=1, and x%5B1%5D=6


m=%285%29%2F%281-6%29 Subtract -2 from 3 to get 5


m=%285%29%2F%28-5%29 Subtract 6 from 1 to get -5


m=-1 Reduce


So the slope of the line that goes through the points and is m=-1
