The high school's enrollment in 2017 is 2500
Step-by-step explanation:
Let's assume time starts since 2009
so, In 2009 , t=0
P=900
In 2012,
t=2012-2009=3
P=1500
(A)
So, we have points as
(B)
we can use slope formula
we can plug values
we know that
slope is rate of change of P with respect to time
so, slope means increase in population is 200 per year
(C)
we can use point slope form of line
(D)
In 2017 ,
t=2017-2009=8
we can plug t=8
and we get
The high school's enrollment in 2017 is 2500
