Question

average thickness of annual rings by age of trees in forest a and forest b
forest a forest b
according to the graph above, which of the following statements best describes the relationship between the age of trees and average thickness of rings in both forest a and forest b?
for both forest a and forest b, as the age of trees increased, the average thickness of their rings increased because they both have positive slopes.
for both forest a and forest b, as the age of trees increased, the average thickness of their rings decreased because they both have negative slopes.
in both forest a and forest b there is no relationship between age of trees and average thickness of their rings because both forests have the same slope.
in forest a as the age of trees increased, the average thickness of their rings increased, but in forest b as the age of trees increased, the average thickness of their rings decreased because the slope is not as steep.

Explanation:

Step1: Analyze the slope of Forest A's line

The line for Forest A has a positive slope. As the age (x - axis) increases, the average thickness of annual rings (y - axis) increases.

Step2: Analyze the slope of Forest B's line

The line for Forest B has a positive slope. As the age (x - axis) increases, the average thickness of annual rings (y - axis) increases.

Answer:

For both Forest A and Forest B, as the age of trees increased, the average thickness of their rings increased because they both have positive slopes.
