The equation for the line of best fit relating the weight of a child in kilograms y in relation to the child's age in years x. W
hich of the following statements is true?y = 3x +3.25
O A The average weight in kilograms is 3 times the age.
OB. The average weight in kilograms is 3 times the height
O C. The average child is 3 years old.
D. The average child weighed 3.25 kg at birth.
It is D because using the equation y=3x +3.25 you can see that the y intercept is 3.25 which means in zero years the child will weigh 3.25 or weighs 3.25 kg at birth.
