Answer 1

To predict the number of miles remaining (y) for a family that has driven for 6 hours (x = 6), we can use the provided linear equation:

\[ y = -60x + 1,200 \]

Now, substitute \( x \) with 6 in the equation:

\[ y = -60(6) + 1,200 \]
\[ y = -360 + 1,200 \]
\[ y = 840 \]

So the predicted number of miles remaining (y) for a family with 6 hours driven is:

\[ y = 840 \]
