Write an expression that represents the height of a tree that began at 6 feet and increas 2 feet per year. Let $y$ represent the number of years. $+\quad y$

Step 1 ：The initial height of the tree is 6 feet.

Step 2 ：For each year, the height of the tree increases by 2 feet.

Step 3 ：Therefore, the expression that represents the height of the tree in terms of the number of years, y, is \(6 + 2y\).
