number 28

The following data shows the price of a certain stock over the last 8 months.

Month	Price
1	2.10
2	1.98
3	2.01
4	1.89
5	1.90
6	1.89
7	1.72
8	1.65

(a)

Develop a scatter diagram and draw a trend line through the points.

A graph has a horizontal axis labeled "Month" with values from 0 to 10 and a vertical axis labeled "Price" with values from 0 to 2.5. The scatter diagram has 8 points. A line goes through the center of the pattern of points. A pattern goes down and right becoming more steep from (1, 1.7) to (8, 1.25).

A graph has a horizontal axis labeled "Month" with values from 0 to 10 and a vertical axis labeled "Price" with values from 0 to 2.5. The scatter diagram has 8 points. A line goes through the center of the pattern of points. The points are scattered from 1 to 8 on the horizontal axis centered at 4.5 and from 1.22 to 1.98 on the vertical axis centered at 1.62.
