least-squares fit line. But when going closer 2. With Show least-squares fit line still selected, set r to 0.90. The points should be close to agcun. the line, but not right on it. Below Generate new data set with: click Same r several times. A. Do all the least-squares fit lines for these scatter plots have the same slope? B. Do all the least-squares fit lines have the same y-intercept? C. What do all the least-squares fit lines have in common? A positive r indicates a positive correlation: as x increases, y also tends to increase. D. Set r to -0.90. Click Same r several times. What do the least-squares fit lines for these scatter plots have in common? A negative r indicates a negative correlation: as x increases, y tends to decrease
