Answer:
Part 1 and 2:  
A.	Forearm (in)        Foot (in)                      
Sarah  	10                9
Sam   11.               10
Emma  8                  7
Mom  	10                 9
Dad  11                 10  
B.	M=9-7 over 8-10 the answer is 2 over 2.
  
C.  For every forearm the foot is one inch smaller.
Part 3:
A.	0.860(17)+3.302
B.	Y=17.922. They are slightly different.  Keren’s has a greater rate.  I think the values are different because they have different origins.
C.	Yes, because it is an important part for rate of change. Yes it is a function because there can’t be any exponents greater than 1, and its not a straight line if you plug it in.
