Question

The scatter plot shows a number of CD's (in millions) that were sold from 1999 to 2005. If the trend continued,about how many CDs were sold in 2006?

A. 900
B.850
C.750
D.650​

Answer 1

D 650 million.
You just have to draw a best fit line? (I forgot what it’s called, and it should be a down word slope)

Answer 2

There 650 million CDs were sold in 2006 if there were 800 million  CDs sold in 2002, and there were 700 million  CDs in 2005 option (D) is correct.

What is a linear equation?

It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.

If in the linear equation one variable is present then the equation is known as the linear equation in one variable.

From the graph:

(2002, 800) and (2005, 700)

We can draw a line for the best fit as follows:

$\rm (y-800) = \frac{700-800}{2005-2002}(x-2002)$

$\rm (y-800) = 33.33(x-2002)$

When x = 2006

$\rm (y-800) = -33.33(2006-2002)$

y = 666.68

Which is near 650 million

Thus, there 650 million  CDs were sold in 2006 if there were 800 million  CDs sold in 2002, and there were 700 million  CDs in 2005 option (D) is correct.
