The Forearm Length in Centimeters, A, Can Be Approximated by a Linear

Multiple Choice

The forearm length in centimeters, A, can be approximated by a linear function of the foot length in centimeters, f. Use the points (25, 24) and (33, 33) to find a linear model for the data in the table below. $\begin{array}{l|lllllllll}\text { Foot Length }(\mathrm{cm}) & 29 & 31 & 33 & 26 & 28 & 37 & 25 & 30 & 32 \\\hline \text { Forearm Length }(\mathrm{cm}) & 30 & 30 & 33 & 25 & 28 & 37 & 24 & 31 & 31\end{array}$

A) $A = f - 1$
B) $\mathrm { A } = 1.125 \mathrm { f } + 4.125$
C) $\mathrm { A } = 1.125 \mathrm { f } - 4.125$
D) $\mathrm { A } = 0.889 \mathrm { f } + 1.775$
