Write the Best-Fit Linear Model for the Data $y = 67.3 + 1.07 x$

Multiple Choice

Write the best-fit linear model for the data.
-The paired data below consist of the test scores of 6 randomly selected students and the number of hours they studied for the test. The linear model for this data is $y = 67.3 + 1.07 x$ , where $x$ is number of hours studied and $y$ is score on the test. Use this model to predict the score on the test of a student who studies 13 hours.
$$\begin{array} { l | l l l l l l } \text { Hours } & 5 & 10 & 4 & 6 & 10 & 9 \\\hline\text {Score}&64&86&69&86&59&87\end{array}$$

A) 86.2
B) 86.8
C) 76.2
D) 81.2
