Answer:
-7/2
Step-by-step explanation:
The slope of a line can be defined as: , which can be more formally calculated as:
, where it's essentially the same thing, except the rise/run is being calculated with two points (which you already need)
So let's just say:
Plugging the values into the equation we get:
You can also just look at the graph and see that from point 1 to point 2, it "rised" -7 units, and "ran" 2 units.
Notice how the "rise" is negative? That just means it went down.
