To predict the number of inches of snow after 10 hours using the equation of the trend line \(y = 1.7x + 0.1\), we can substitute \(x\) with 10.
\[ y = 1.7(10) + 0.1 \]
Now, calculate:
\[ y = 17 + 0.1 = 17.1 \]
After rounding to the nearest tenth, the predicted snowfall after 10 hours would be 17.1 inches.
