The average monthly temperature and the average wind speed in a particular location was plotted over several months. The graph shows the points for each month’s data and their line of best fit.

Loading Graph...

A scatter plot is displayed with temperature (°C) on the horizontal axis, ranging from 0 to

10

, and wind speed (knots) on the vertical axis, ranging from 0 to 8. A series of black dots represent individual data points plotted on the graph. The data points show a decreasing trend from the top left to the bottom right. A straight line descends diagonally across the plot, suggesting a linear relationship as it passes through the scattering of points. The line passes through points $\left(0,8\right)$(0,8) and $\left(10,2\right)$(10,2), but is not explicitly given in the image.

Use the line of best fit to approximate the wind speed on a day when the temperature is $5$5°C.
