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, 5); (5, 8); (10, 8); (12, 9); (15, 11); (15, 14); (18, 11); (21, 13); (21, 16); (25, 15); (25, 18); (30, 17); (30, 20); (35, 20); (42, 23); (42, 25); (50, 27); (50, 29). The points generally rise from left to right at a constant rate. Question content area bottom Part 1 Do the two variables have a linear relationship? A. The data points have a linear relationship because they do not lie mainly in a straight line. B. The data points do not 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
