For graph A , r is closer to 1 . For graph B, r is closer to 0.

The "r" value refers to the correlation coefficient. It measures the direction and strength of relationship between two variables.

For graph 1, the pattern or trend is well defined and linear. The graph slopes upward which means we'll have a positive r value and the r value would be close to 1 . Hence, signifying a positive and strong relationship.

For graph 2, The points are scattered with no defined trend or direction. This infers that the correlation coefficient would be close to 0. Signifying that there is no relationship between the variables.
