The table shows the linear relationship between the average height in feet of trees on a tree farm and the number of years since the trees were planted.What is the rate of change of the average height in feet of the trees on the farm with respect to the number of years since the trees were plant

A 9 ft/yr
B 27ft/yr
C3ft/yr
D 12ft/yr

To find the rate of change of the average height of the trees with respect to the number of years since they were planted, we can look at the slope of the line that represents the relationship.

From the table, we can see that for every 3 years since the trees were planted, the average height of the trees increases by 9 feet.

Therefore, the rate of change is 9ft/3yr = 3ft/yr.

The correct answer is C. 3ft/yr.
