Answer:
The rate of change of the graph is
⇒ answer B
Step-by-step explanation:
- The graph represents a linear relation between the number of
songbird and the number of birds of prey
* x-axis represents the number of the songbirds
* y-axis represents the number of birds of prey
- The rate of change is represented by the slope of the line
- The rule of the slope of a line is:
, where
and
are two points lie on the line
- Let us find two points lie on the line from the attached figure
∵ Points (0 , 0) and (14 , 4) lie on the line
- By using the rule of the slope
∴ 
∵ The slope of the line represents the rate of change of the graph
∴ The rate of change of the graph is
