A certain type of tree was 10 feet tall in 2005. By 2011, the same tree was 7 feet tall. Assuming the tree's height decreased at a constant rate, which of the following linear functions $h$ best models the tree's height, in feet, $t$ years after the year 2005?

A.

$h (t) = - \frac{1}{2} t + 10$

B.

$h (t) = - \frac{3}{6} t + 7$

C.

$h (t) = \frac{1}{2} t + 10$

D.

$h (t) = - \frac{1}{2} t + 7$
