What is the equation in point−slope form of the line passing through (2, 2) and (4, 8)?

answers:

(y − 2) = 3(x − 2)

(y + 2) = 3(x + 2)

(y − 8) = −3(x − 4)

(y + 8) = −3(x + 4)

Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 25002500 grams and a standard deviation of 800800 grams while babies born after a gestation period of 40 weeks have a mean weight of 27002700 grams and a standard deviation of 385385 grams. if a 3232-week gestation period baby weighs 21252125 grams and a 4040-week gestation period baby weighs 23252325 grams, find the corresponding z-scores. which baby weighs lessless relative to the gestation period?
