The linear equation will be y=34x+12 and the slop is 34 and y intercept is 12. And the sunflower will be 420 inches tall after a year.
Here, the sunflower was 12 inches when first planted and it grows 34 of an inch each month
So, the linear equation will be
y=34x+12
Where,
y=height
x=month
now,
the slope-intercept equation is
y=mx+c
Where,
m=slope
c=y intercept
Comparing this equation with equation (1)
We will get
m=34
c=12
so, the slope is 34 and y intercept is 12.
now,
The tree is 12 inches when it first planted and since then it grows 34 of an inch every month
So,
Height of tree after a year =12+34×12
Height of tree after a year = 12+408
Height of tree after a year = 420 inches.
Hence,
The tree will be 420 inches tall after a year.
