O There appears to be a negative linear relationship between x and y. O There appears to be a positive linear relationship between x and y. O There appears to be no noticeable relationship between x and y. (c) Try to approximate the relationship between x and y by drawing a straight line through the data. y y y y 18+ 18- 18+ 18+ 15 15 15 15- 12- 12 12 12 9 9. 91 9 6- 6- 6- 3- 3- 3+ 3- 3 4 5 6. 2 3 4 5 6. 4 5 6. 1 2 4 5 6.
