Use a graphing utility to find the equation of the line of best fit. Round to two decimal places, if necessary.
-Two different tests are designed to measure employee productivity and dexterity. Several employees are randomly selected and tested with these results. $\begin{array}{l|l|l|l|l|l|l|l|l|l}
Productivity&23 & 25 & 28 & 21 & 21 & 25 & 26 & 30 & 34 & 36 \
Dexterity&49 & 53 & 59 & 42 & 47 & 53 & 55 & 63 & 67 & 75
\end{array}$

A) $\mathrm { y } = 75.3 - 0.329 \mathrm { x }$
B) $y=10.7+1.53 x$
C) $y = 5.05 + 1.91 x$
D) $y = 2.36 + 2.03 x$
