Use a graphing utility to find the equation of the line of best fit. Round to two decimal places, if necessary.
-$\begin{array}{c|cccccc}
\mathrm{x} & 1 & 2 & 3 & 4 & 5 & 6 \
\hline \mathrm{y} & 17 & 20 & 19 & 22 & 21 & 24
\end{array}$

A) $y = 1.17 x + 16.4$
B) $y = 1.03 x + 16.4$
C) $y = 1.03 x + 18.9$
D) $y = 1.17 x + 18.9$

Quizplus · Accepted Answer

Using a graphing utility to perform a linear regression on the given data points, the line of best fit is found to be $y = 1.17x + 16.4$, which matches choice A. This equation is derived by calculating the slope and y-intercept that best approximate the relationship between the x and y values in the dataset.
