Will give brainliest for most detailed ! x (arm) y (foot) 7 5 9 9 9 8.5 8 7 10 9 part 3 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. 7 = 0.860 x 5 + 3.302 = 7.602 9 = 0.860 x 9 + 3.302 = 11.042 9 = 0.860 x 8.5 + 3.302 = 10.612 8= 0.860 x 7 + 3.302 = 9.322 10 = 0.860 x 9 + 3.302 = 11.042 using this equation, how long would the foot of a person be if his forearm was 17 inches long? 17= 0.860 x 15.93 + 3.302 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.
