100 POINTS!!!!!!!!!!!!!!! HELP ME IM DESPRATE!!!!! IL GIVE BRAINLY AND MAYBE EVEN HELP YOU OUT ON YOUR QUESTIONS!!!!


I have these measurements for A forearm and Foot as Functions.
10, 9
11, 10
9,12
12,11

WHAT I NEED HELP WITH: Select two sets of points and find the rate of change for your data.

Describe your results. If you had to express this relation as a verbal statement, how would you describe it?


e equation below can be used to find the length of a foot or forearm when you know one or the other.

(length of the foot) = 0.860 • (length of the forearm) + 3.302

If you let y = length of the foot and x = length of the forearm, this equation can be simplified to
y = 0.860x + 3.302.

Using this equation, how long would the foot of a person be if his forearm was 17 inches long?

What is the rate of change of the equation from Part A?

Compare the equation from Part A to your data. Are they the same? Which has a greater rate of change? Why do you think the values are different?

Is the relation in your data a function? Why or why not? Could the equation in Part A represent a function? Why or why not? Explain your answer.



PLEASE HURRY!!!
