Michael owns an apple tree orchard. Every time he plants a new tree, he measures its height and then tracks its growth on a graph. When he first planted this tree, it was 2 feet tall. A year later, the tree was 6 feet tall.

Part A: What is the y-intercept for the graph? What does it represent?

• (0, 10); the height the tree reached at 2 years

• (0, 0); the height of the tree at 0 years

• (0, 2); the height when he first planted the tree

• (0, 6) The height the tree reached at 1 year

Michael owns an apple tree orchard. Every time he plants a new tree, he measures its height and then tracks its growth on a graph. When he first planted this tree, it was 2 feet tall. A year later, the tree was 6 feet tall.

Part B: What is the slope of the graph? What does it represent?

• 2, the height of the tree when it was first planted

• 4, the tree grows 4 feet every year

• 6, the tree grows 6 feet every year

• 5, the tree grows 10 feet every 2 years

Michael owns an apple tree orchard. Every time he plants a new tree, he measures its height and then tracks its growth on a graph. When he first planted this tree, it was 2 feet tall. A year later, the tree was 6 feet tall.

Part C: Which equation represents the growth of Michael's tree?

• y = 2x + 6

• y = 6x + 2

• y = 2x + 4

• y = 4x + 2
