Kris planted a tree in his yard when it was 3 feet tall. Each year the tree grows a foot. What is the rule that represents this situation?

• y=x+3

• y=3x+1

• y=3x

• y=x+1

What does the y-intercept in the rule for Kris' tree represent?

• The starting height

• The growth

• Nothing

If the rule for Kris' tree is y=x+3, how long until it is 20 feet tall?

• 17 years

• 23 years

• It won't

• 6 years
