Use the given data to find the equation of the regression line. Examine the scatterplot and identify a characteristic of the data that is ignored by the regression line.

x	5	8	11	6	9	13	12	4	3	7	10
y	6.94	10.00	10.54	8.24	10.45	9.51	10.16	5.36	3.51	9.25	10.64

A scatterplot has a horizontal x-scale from 0 to 25 in intervals of 1 and a vertical y-scale from 0 to 25 in intervals of 1. Eleven points are plotted with approximate coordinates as follows: (3, 10.5); (4, 10.5); (5, 3.5); (6, 8); (7, 10); (8, 5.5); (9, 9.5); (10, 9.5); (11, 7); (12, 10.5); (13, 10).

Identify a characteristic of the data that is ignored by the regression line.

There is no trend in the data.

There is an influential point that strongly affects the graph of the regression line.

The data has a pattern that is not a straight line.

There is no characteristic of the data that is ignored by the regression line.
