Consider the table of data and scatter plot regarding the cherry blossom trees in Washington D.C. What is the correlation between the temperature and the date in April the trees bloom?

Carl wants to know if he is improving his skills on the cello. He created a scatter plot and drew a line of best fit. If he uses the point (2, 8) and (5, 1.5) from his line, which equation would best represent the line of best fit? (Hint: examine the line and graph)

• y= -2.17x + 12.3

• y= 2.17x + 12.3

• y= -0.46x +9

• y= -2.17x - 9.35
