A meteorologist collected data on a recent snowfall. The meteorologist graphed the data and found the equation of the trend line to be y = 1.7x + 0.1. If the snowfall continues at this pace, use the equation to predict the number of inches of snow after 10 hours.
To answer this question, we need to plug in x = 10 into the equation and solve for y:
y = 1.7x + 0.1
y = 1.7(10) + 0.1
y = 17 + 0.1
y = 17.1
Therefore, if the snowfall continues at this pace, we can predict that there will be approximately 17.1 inches of snow after 10 hours.

To predict the number of inches of snow after 10 hours, we can use the equation of the trend line: y = 1.7x + 0.1.
In this equation, y represents the number of inches of snow, and x represents the number of hours.
To find the predicted number of inches of snow after 10 hours, we substitute x=10 into the equation:
y = 1.7(10) + 0.1
Simplifying the equation, we get:
y = 17 + 0.1
y = 17.1
Therefore, based on the trend line equation, the prediction is that there will be approximately 17.1 inches of snow after 10 hours.
