Question

interactive practice: graph proportional relationships and define slope
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?
what is the slope of the line?
without otters: 14
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 increase carbon dioxide absorption by kilotons per day.

Explanation:

Step1: Identify the slopes

The slope for without otters is \(14\) and with otters is \(20\).

Step2: Calculate the difference

To find how much otters increase carbon - dioxide absorption, we subtract the slope without otters from the slope with otters. The formula is \(20 - 14\).

$$20-14 = 6$$

Answer:

Otters increase carbon dioxide absorption by \(6\) kilotons per day.
