The scatterplot shows the recommended dosage of Vitamin D throughout the life of a person. Which equation best represents the line of best fit?

Responses
A y =

xy = 1 5 x
B y =

x + 2y = 1 5 x + 2
C y =

x − 2y = 2 5 x − 2
D y = −

x + 2

Without the scatterplot or any specific data points, it is not possible to determine the equation that best represents the line of best fit. The equation for the line of best fit would be determined using regression analysis based on the actual data points.
