Quick Method: The y coordinates are the same. Therefore, the slope is 0. Visually, this is a horizontal line (and all horizontal lines have slopes of 0)

=======================================================

Longer Method:

Note: is the first point . So this means that x%5B1%5D=5 and y%5B1%5D=-2.
Also, is the second point . So this means that x%5B2%5D=-4 and y%5B2%5D=-2.


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


m=%28-2--2%29%2F%28-4-5%29 Plug in y%5B2%5D=-2, y%5B1%5D=-2, x%5B2%5D=-4, and x%5B1%5D=5


m=%280%29%2F%28-4-5%29 Subtract -2 from -2 to get 0


m=%280%29%2F%28-9%29 Subtract 5 from -4 to get -9


m=0 Reduce


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