The table shows the total snow depth y (in inches) on the ground during a snowstorm x hours after it began. Use a graphing calculator to find an equation of the line of best fit. Identify and interpret the correlation coefficient. Use your equation to estimate how much snow was on the ground before the snowstorm began. Round the slope to the nearest tenth, the y-intercept to the nearest whole number, and the correlation coefficient to the nearest thousandth.

Equation of the line of best fit: y=

Correlation coefficient: r≈

There were
inches of snow on the ground before the snowstorm began.

Question 2
There is
correlation between the variables x and y and the equation
the data.
