Answer: The correct answer is the third choice.
Step-by-step explanation: The question is asking you to look at pieces of data from the graph. The best way to do this question is to look at each question to determine whether the statement is true or false.
In looking at the each choice:
First one - The statement is true. Looking at the graph, a 40 and 50 year old person has the same average rate.
Second - The statement is true. Looking at the graph, you can see a steady decline from a 10 year old to a 20 year old person.
Third - The statement is false. A 10 year old and 20 year old do not have the same rate.
Fourth - The statement is true. A 20 and 30 year old have the same heart rate.

Answer:
Rate of change is 6/7 Initial value: 6
Step-by-step explanation:
To find the slope (which is the rate of change), use (y1 - y2)/(x1 - x2).
x1 and y1 will be (0, 6)
x2 and y2 will be (7, 0)
Note that x1 x2 y1 y2 can be any points on the line, I just chose these because they were x and y-intercepts.
(6 - 0)/(0 - 7) = 6/7
The initial value is simply the y-intercept, which is 6.
Question 4 is (1,2)
Question 5 is (1,0)
These are are definitely correct
