PLS HELP WILL GIVE BRAINLIEST & 100 POINTS PLEASE GIVE CORRECT ANSWER!!!
Part 1: The 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?

Part 2: What is the rate of change in the equation from Part 1?

My Data:
Foot Length Forearm length
7 9
8 10
9 11
10 12
11 13
Rate of Change: 2

Compare the equation from Part 1 to your data. Are they the same? Which has a greater rate of change? Why do you think the values are different?

Part 3: Is the relation in your data a function? Why or why not? Could the equation in Part 1 represent a function? Why or why not? Explain your answer.
