Answer 12

is this step b?

Answer 13

Yes

Answer 14

ok...
i got
1/1

Answer 15

so the rate of change is 1

Answer 16

ok! and part c?

Answer 17

Relation, you can say that as x increases by 1, y increases by 1 as well.

Answer 18

Answer 26

Compare rates of change.

A. 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?

B. 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?

C. 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.
