The coordinate points below show part of the data collected by the cell phone company, where x is age in years and y is texting speed in words per minute.
(12, 16), (13, 18), (13, 10), (14, 16), (15, 9), (15, 8), (16, 17), (17, 23)

If this data was plotted on a scatterplot, would there be a relationship between the variables? If yes, explain the relationship.
Yes, there is a relationship. As age increases, texting speed also increases.
Yes, there is a relationship. As age increases, texting speed decreases.
Yes, there is a relationship. As texting speed decreases, age also decreases.
No, there is no clear relationship between age and texting speed.

Plot points (12, 16), (13, 18), (13, 10), (14, 16), (15, 9), (15, 8), (16, 17), (17, 23) on the coordinate plane. On this coordinate plane x represents age in years and y represents texting speed in words per minute.

Option A is false. Consider points A(12,16) and C(13,10). For these points x-coordinates increases, but y-coordinates decreases. Therefore, as age increases, texting speed doesn't increase.

Option B is false. Consider points A(12,16) and B(13,18). For these points both x-coordinates and y-coordinates increases. Therefore, as age increases, texting speed increases too.

Option C is false. Consider points C(13,10) and F(15,8). For these points y-coordinates decreases, but x-coordinates increases. Therefore, as texting speed decreases, age increases.

Option D is true, there is no clear relationship between age and texting speed.
