Question

Six years after a tree was planted, its height was 7 feet. Nine years after it was planted, its height was 16

feet. Which of the following equations gives the heighty, in feet, of the tree after x years if the tree grows at
a constant rate? Check all of the boxes that apply.
y - 6 =3(x - 10)
y-16 = 3(x-9)
y = 3x - 11
y=-3x - 23

Answer 1

I'm not good in this but.....

x = years

9x-6x = 16-7

3x = 9

x = 3

That means the tree will grow three feet per year.
