A regression line cannot help predict future values of variables.



Scatter plots can be used to represent quantitative data.

Answer 1

The answer is letter D.

Answer 2

1.The Line may pass through all the points , a single point or none of the points.

2. It can also predict the future values that is for given x , we can find y and for given y , we can find x.

So, only option (4) which is,Scatter plots can be used to represent quantitative data is true.
