During a science lab, students heated water, allowed it to cool, and recorded the temperature over time. They computed the
difference between the water temperature and the room temperature. The results are in the table. $$\begin{array} { | l | l | l | l | l | l | l | }
\hline \text { Time (in minutes) } & 10 & 20 & 30 & 40 & 50 & 60 \
\hline \text { Difference in temp. (degrees F) } & 68 & 36 & 20 & 10 & 6 & 4 \
\hline
\end{array}$$
-Write the equation of the least-squares regression line for the transformed data. Draw the
regression line on the scatterplot in question 2.
