- 19. Multiple ChoiceMiss Brill wants to know if she is improving on her skill on the clarinet. She created a scatter plot and drew a line of best fit.
If she uses the point (2, 8) and (5, 1.5) from her line, which equation would best represent the line of best fit?y= - 0.46x + 9y= -2.17x + 12.3y= -2.17x + 3.77y= -2.17x - 9.35 - 20. Multiple ChoiceThe graph above shows a line of best fit for the data collected on the price of a unit in relation to the number of units sold. What is the equation of the line of best fit?y= (-1/50)x + 40y= (1/2)x + 40y= (2/100)x + 40y= (-1/2)x +40

- 23. Multiple ChoiceMartin and Daisy are arguing about which graph below represents a non-linear relationship. Martin believes Graph A represents a non-linear relationship, but Daisy thinks it is Graph B. Which of the following statements explain who is correct and why?Graph A, because a trend line cannot be drawn through the data pointsGraph B because a trend line cannot be drawn through the data points
- 24. Multiple ChoiceWhich scatter plot shows a linear relationship between x and y?Graph AGraph BGraph CGraph D
