Determine whether the scatter diagram indicates that a linear relation may exist between the two variables. if the relation is​ linear, determine whether it indicates a positive or negative association between the variables. use this information to answer the following. 0 20 40 0 10 20 30 explanatory response a scatter diagram has a horizontal axis labeled “explanatory” from 0 to 40 plus in increments of 10 and a vertical axis labeled “response” from 0 to 30 in increments of 5. the following 18 approximate points are plotted, listed here from left to right: (5, 4); (5, 7); (10, 7); (12, 9); (15, 10); (15, 7); (18, 10); (21, 12); (21, 15); (25, 14); (25, 17); (30, 16); (30, 19); (35, 19); (42, 22); (42, 24); (50, 26); (50, 29). the points generally rise from left to right at a constant rate. do the two variables have a linear​ relationship? a. the data points do not have a linear relationship because they do not lie mainly in a straight line. b. the data points have a linear relationship because they do not lie mainly in a straight line. c. the data points do not have a linear relationship because they lie mainly in a straight line. d. the data points have a linear relationship because they lie mainly in a straight line.
