Question

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?

Answer 1

The answer to your problem is, -3000

Explanation:

:Write down the points through which the line passes through

:The line is passing through a point at (0, 80000) and (10, 50000)

Next, ( important )

Find the slope of the line

Since the line is passing through the point (0, 80000) and (10, 50000)

So the slope of the line:

= m

`(80,000 - 50,000)/(0 - 10)`

=
`(30,000 )/(-10)`

= -3,000

Techniquelly the answer is, 30,000 but for more explanation here it is :)

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

The required point-slope equation that models this scenario is

`y - y_(1) - m( x - x_(1) )`

y - 50,000 = -30,000 ( x - 10 )

Thus the answer to your problem is, - 3,000
