Solution
1987 the population is 33600
1996 the population is 27300
Linear equation is y=mx+c
P=33600 - mt
27300 = 33600 - mt
27300- 33600= -mt
-6300= -9t
Dividing both sides by -9
T=700
The linear equation is
P = 33600- 700t
PART B
T= 2000 - 1987
T= 13
The population in 2000 is
P = 33600- 700(13)
P = 33600 - 9100
P = 24,500
