Question 1137458: The average weight of a male child’s brain is 970 grams at age 1 and 1270 gams at age 3.
i.Assuming that the relationship between brain weight y and age t is linear,write linear model for the data.
ii. What is the slope and what does it tell you about brain weight?
iii. Use your model to estimate the average brain weight at age 2?
iv. Search the net to find the actual average brain weight at age 2. How close is your estimate?
v. Do you think your model could be used to determine the average brain weight of an adult? esplain

(1, 970) & (3, 1270)

y-970=%28%281270-970%29%2F%283-1%29%29%28x-1%29
y-970=150%28x-1%29
y=150x-150%2B970
highlight%28y=150x%2B820%29

Increases at rate of 150 grams per year (slope)
