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.

Correct choice is D

Step-by-step explanation:

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.
