Answer: The slope is 3/2
Step-by-step explanation:
To find the slope, you need to find the difference between the y coordinates and divide it by the difference in the x coordinates.
The y coordinates are -4 and 5
The x coordinates are -4 and 2
-4 -5 = - 9
-4 - 2 = -6
-9/-6 = 3/2
Answer:

Without needing fancy formulas, we can conclude that after 10 years, half of the substance will be left. So, we can make our own formula:
amount remaining = 1 / 2^(years/10)
So, after 5 years
amount remaining = 1 / 2^(5/10)
amount remaining = 1 / 2^(.5)
amount remaining = 1 /
