A team of forestry specialists from the Newton lumber company visited a section of the forest that was going to be logged for timber. They took measurements to evaluate the health and growth of trees in the area.

The team counted the number of rings on several trees to find their ages (in years), x. They also measured the diameter of these trees (in meters), y.
The least squares regression line of this data set is:
y=0.009x–0.124

If a tree were one year older, the least squares regression line predicts that its diameter would be _____________
meters larger.

0.009 meters
