Answer:
m (slope) = -5
Explanation:
All you need to do is use 2 of these points. For this example, we will use
(13,11) and (14,6).
To solve, use rise/run. The y value (rise) goes down by 5, so your rise is -5. The x value (run) goes up by 1, so your run is 1.
Insert these values into rise/run to get -5/1. Simplify this to get -5.
