, 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.
Answer:
3½
Step-by-step explanation:
c/2 - 3 + 6/d
14c = 14
c = 1
3d = 3
d = 1
c/2 - 3 + 6/d
1/2 - 3 + 6
3½
