Megan measures the height and arm spans of the girls on her basketball team. She plots the data and makes a scatterplot comparin
g 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
A. Y = 64-2 = 62 inches
B. y = 64+2 = 66 inches
C. y = 64 inches
D. 64 = X +2

Step-by-step explanation:
Dilation in this context is the transformation is an object into a larger one.
ABC is transformed to A'B'C'
To get the scale factor, we divide the coordinates of A'B'C' by ABC
i.e
A'/A = -28/-7, 32/8 = 4
Or
B'/B = 4/1, -28/-7 = 4
Or
C'/C = 28/7, 24/6 = 4
