Question

dr. castillo analyzes the carbon absorption in kelp forests with and without otters. she makes a graph to compare the carbon absorbed in each type of kelp forest, in kilotons per day.
what is the slope of the line?
without otters: 14
what is the slope of the line?
with otters: 20
what do the slopes mean in this situation?
kelp forests without otters absorb carbon dioxide at a rate of 14 kilotons per day.
kelp forests with otters absorb carbon dioxide at a rate of 20 kilotons per day.
how do otters affect carbon dioxide absorption in kelp forests?
otters? carbon dioxide absorption by? kilotons per day.

Explanation:

Step1: Find the difference in slopes

The slope without otters is 14 and with otters is 20.
$$20 - 14$$

Step2: Calculate the value

$$20-14 = 6$$

Answer:

Otters increase carbon dioxide absorption by 6 kilotons per day.
