Answer:
-1/1
Step-by-step explanation:
Use the rule rise over run. When you 'rise', you count up, or in this case down, until you reach a point that crosses a point (the point can not go directly through an increment, ie. [1, 5/4]). When rising, note that you won't directly reach that point. That's where 'running' comes in. 'Run" towards the point. Make sure to count your rises and run to get your slope:
Rise/run
Read the graph left to right to determine if it is negative or positve. If the graph is going down, like it is in this graph, it's negative.
