Four years after a tree was planted it was 8ft tall. 8 years after it was planted it was 12ft tall. What is the growth rate of the tree? how tall when planted?

Please use y=mx+b and coordinates we are doing slope in algebra one

Mikaila D.

We can think about the number of years as x, and the height of the tree as y, because the tree's hight depends on how many years has passed.

Using this, we have two points. (4, 8) and (8, 12)
 
I think this should help you answer the question.
