Megan measures the height and arm spans of the girls on her basketball team. She plots the data and makes a scatterplot comparing heights and arm spans in inches. Megan finds that the trend line that best fits her results has the equation y = x +2. If a girl on her team is 64 inches tall, what should Megan expect her arm span to be.
A. Y = 64-2 = 62 inches
B. y = 64+2 = 66 inches
C. y = 64 inches
D. 64 = X +2
X = 62 inches
