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.

Answer:
1600
growth
4%
Step-by-step explanation:
To solve this question, you must know what the equation really means.
P = population
t = time
1600 = initial population size
1.04 = is the percentage growth, (growth because it is greater than 1.)
So, the initial population size is 1600.
It is growth because the percentage is greater than 1.
(1.04 = 104%, 104%-100%=4%)
The population changes by 4%
