The newspaper in haventown had a circulation of 80,000 papers in the year 2000. in 2010, the circulation was 50,000.
with x = 0 representing the year 2000, the graph below models this scenario.

What number will complete the point-slope equation that models this scenario?

y -50,000 =______(x -10)

A.) -3,000

B.) -2,000

C.) 2,000

D.) 3000

Answer : A.) -3,000

x = 0 representing the year 2000, circulation was 80,000.

x =10 representing the year 2010,circulation was 50,000.

Point slope equation is

, where m is the slope and (x1,y1) is one of the point

We have two points, (0,80000)  and (10,50000)

Now we need to find slope (m)

=

So answer is y -50,000 =-3000(x -10)
